Two hole pistons only have two holes which based on their size will make the shock feel a bit thicker. Adding an additional hole will help to move through the oil a bit easier which in turn makes the shock feel like you are running thinner oil. All of this however can be adjusted based on the size of the holes. AE offers four different options in pistons...
1) #1 Piston with two 1.40mm holes
2) #2 Piston with two 1.32mm holes
3) #3 piston with two 1.19mm holes
4) Blank pistons with no holes (so that you can drill your own)
I typically run and like the feel of three hole pistons, so I run #3 with an extra 1.5mm hole drilled in it.
I have tried the Losi pistons, but usually end up with the AE pistons back in. Simply the shock was designed around the AE piston shape and I think the Losi pistons create a different feel with additional blow by around the outer edge. All of the is very hard to feel on the track, but on the bench I can tell. I would think it would take a very good driver on a very consistent surface to honestly feel the differences between #1 and #2 pistons with the same oil.
