    Opinions please.

    I'm in the market for an Iwata HP-B+ to complement my HP-C+ for finer work. I build scale models typically with acrylics, but also some lacquers. I thought after that, I'd get a CM-B v2 for extra fine detail. But it occurred to me I might not need both. Instead of buying both, would I be fine with just one or the other? Should I just save and buy the Micron (still pissed I missed buying Bryan 71's CM-B but my fault for not checking sooner) as it will do pretty much what the HP-B will only finer, or should I only get the HP-B as the Micron might be overkill and I'm not proficient enough to get the full benefits of the Micron?

    I also have an Infinity with both .2 and .15 needles and nozzles, so should I even bother considering the Micron?

    Thoughts?

    the HP B+ actually comes real close to the micron B in fact if your airbrush control is good you can do real fine detail with a HP + version I own both the HP SB+ as the CM SB v2 and there is little to no difference to what I can do with those airbrushes I admit it is easier with the micron but really not much and with the @Dave G. setup and the SN 1 needle I would say the HP is just as good as the CM

    That’s your answer, I didn’t saw any difference between my microns and my infinity other than the personal preference for the feel in my hand. And as Ronald said, once you are able to do fine line with one brush you can do it with any other, the only difference between them are just plain preference.

    I now have the new V2 needles for the Infinity, but haven't really put them through their paces. I've gotten about .4 mm lines out of the old .15 needle using Mission Models Paints, so I would imagine I should be able to do at least as good with the V2.

    Once your more experienced the HP-B will do what you want, it’s just a matter of practise and getting your paint & PSI dialled in to that sweet spot.
    If you’re really keen to get a micron the the one husky linked to has some great reviews.
    Just to throw you into a spin, I actually get finer lines from my Iwata CM-SB v2 than my CM-B v1

    Hehehehe, I have them all - every brush listed in this conversation ;).

    A good bit of my recommendation will lay within your ability to use a brush, and your willingness to learn more about how your particular brush works. If you just want to buy a brush, and have it fit most of the criteria you listed, I would say look at the GSI Creos PS770. Right out of the box, it is an awesome piece. Micron quality inside and out, with specs that make it perform just as well as many of the top named brushes. Especially as it falls in a price range that will not break the complete bank.

    Now, if you don't mind putting in the time to really learn a brush, and what it is willing to do when treated right, I would go for an HP-B or B+. I have been working with them a lot as of late, and find that I can get very similar results to that of a Micron, but with a brush that seems to be more forgiving, and less prone to clogging if conditions are not 100% perfect for it. They can be cheaper to maintain over the long run than a Micron, as the repair parts for Microns is really starting to skyrocket out of control.

    All kidding aside, I have a fair collection of brushes, and the one I reach for more often than any other is something from the HP line of Iwata's - usually the HP-B (or Plus - to me they are the same).

    I had considered the PS-770 - thank you too Vladimir for the suggestion - and hadn't quite ruled it out, but if the HP-B Plus will perform as well as the Micron, then I'd go for the lower priced HP-B Plus. I wanted to get some opinions first on where they all fall in terms of control and fine lines.

    My Infinity took some work to get it to maximum performance (and it still had its moments, which is why I'm liking the Iwatas more), so I'm not adverse to putting in the time. It's sounding like the HP-B Plus would be the best balanced choice (cost vs performance).

    What was Ronald art referring to when he talked about the DaveG. setup? I've seen the SN 1 on the for sale page, but what did he mean Dave by your setup? What else could I do to the HP-B to maximize its performance?

    Thanks Jack - it's looking like I'm going to go with the HP-B Plus. But who is Husky and the link you mentioned? I don't see a Husky in this thread. Or did you mean Vladimir?

    Oh, I work a lot with this series of brush (the HP). I make the same type of internals that a Micron has, along with a few different triggers. Wind my own needle and trigger springs, and had a nearly indestructible seal made to replace the teflon - all leading to a highly adjustable brush, which allows a user to make it feel the way they need it to. I am working a BUNCH with the business end, different needle/nozzle/nozzle cap configurations to tailor the brushes performance to the task...

    Ok I want that kit. Maybe two - one for the HP-B and one for the HP-C. How do I get it and how much? Does it come with instructions?

    hahahaha, we have us someone with AAD (Airbrush Acquisition Disorder - welcome;))

    I make the parts in small batches and put them up for sale when they are ready. I do it because I want to, and for fun, which means that I may not have what you want, when you want it :). The HP-B, and C use different parts, being that they are completely different sizes throughout.

    You can follow my FB page - https://www.facebook.com/davegs.airbrush.exploration/
    or try dropping me a PM for more details.

    Yes, I'm a bit of a tool whore. And I know there's no logical reason for it when it comes to airbrushes, but looks count to me. It's why I never leapt immediately on the PS770 - it just ain't pretty enough :)

    But I am interested in customisation to enhance flow and control, particularly if it tweaks overspray. You'll be hearing from me soon Dave. And thanks again!

    By the way Dave, have you any mods for the Infinity to improve performance?

    I can speak to what the DaveG tune up parts wise can do. I have tuned a spare Olympos 100SB with the Iwata HP-SB fluid nozzle and needle and a nozzle cap with DaveG's trigger. Totally changes the nature of the brush and a worthy stablemate for my Micron SB. Don't hesitate to buy parts from Dave as it will be money well spent and likely become a regular "go to" when buying vintage airbrushes to mod.

    I did it once. There's no reason for it, nothing about your accounts are similar.

    After awhile all the posts blur into one and it’s all just white text on a black background... downside of being a mod, I read EVERYTHING
