This is a personal preference type of thing. Some people love it...some don't even notice. LOL. When you buy spare parts order some extra pistons, they're cheap, so you can go back if you don't like the drilled ones. My guess is you'll be just fine with drilled pistons. Here's the drills from Racers Edge
