I found that more or less rounded tops give indeed more grip an even more if there are groves on the top but I have slightly different needs and I guess a lot depends on the materials used right now I am very happy with the olympos F1 trigger it gives me just enough grip not to slip ff it and the trigger responds to the slightest movements of my finger but it took me a few hours to get used to that quick response after working with the V2 trigger for over 2,5 years
