The 2 hole pistons just felt the same all the way around.
I know Hiro has been doing some testing with the 2 hole pistons again, and he seems to like them. I run them when the grip is very high, because it seems to make the car more consistent. The 3 hole pistons tend to make the car very reactive initially, but they can make the car feel odd when the grip is very very high unless used in combination with very thick oil.
This is just what I have found though. Id say it's worth a try for yourself as well. It really depends on how much static grip the track has. That can influence the results drastically.
