Rebound is one i dont fully understand myself, so i just build all mine with as little as i possibly can.

Pistons, it depends how seriously you take your racing i guess. You can settle one a set you like and just adjust your oil, but there is more to it than that. The more holes you have in your pistons, the more "pack" there is. Basically this is disruption to the sitting oil as the piston suddenly moves. THe more pack there is, the more resistance there in on a sudden impact. For example, if you have 2 cars, one with 2 hole pistons in, and another with 4 hole pistons in and drop them both from the same height, the one with 2 holes will compress easier and land softer than the one with 4 holes. I would say its more a tuning aid for the track you are on. Less pack for smaller jumps, more for those where ure car is going to be landing harder.

Bladders, i hate them personally. I prefer the bleed screw type shocks. But i cant tell you the pros and cons of each, other than bleed screw are easier and quicker to build for me.

Im sure if i have left anything out or got anythin wrong then someone wil add to this
