What are the most reliable pistons out there where you can get a little more performance w/o spending the money on OEM. I am right now debating whether to buy a pro circuit Athena piston from TT, or the wiseco that comes in the kit from motosport outlet. Whats the difference between 2095 silicium which is said to be used in formula one pistons and the forged aluminum wiseco pistons? Which way am I better of going? I really want to try the Athena but I don't know what to expect. Which would be more realiable? Anyone have experience?
