Wiseco is a damn good piston, it just needs a little work before its assembled in an engine(so does the JE IMO). The JE is the lightest out of the bunch but the reason why is the crown of the piston is the thinnest and the skirt is the shortest......which sometimes is a good thing lol but sometimes not in all applications. The CP and Wiseco are about the same weights but the CP has a better wristpin fitment out of the box. All need the gaps done on the rings, Ive never been able to install rings out of the box......never. The CP is the best overall but is also the most expensive, the best bang for the buck is the Wiseco, the lightest is the JE. The JE has the least amount of valve clearance especially in a milled cylinder application and with the crown being as thin as it is its not the best pick if milling is planed. All are just as durable as the other IMO.
