as far as quality of piston...composition and attributes there is no better piston than CP. budget minded id go with Wiseco. I have a new CP piston that i have altered to my specifications that I could have made for you in 2-3 weeks. Both mind you are great pistons however the best out are CP....they do cost more but if you want to see the differences in why shoot me an email. i can show you the important ques to look for. Wisecos being a cheaper piston (price wise) will be quite suitable for your needs. It all boils down to cost and what you are more budgeted for.
