| I'm partial to Wiseco only because I was involved in their design, but the others you mentioned have proven themselves to be non-problematic. What is really critical is your piston-bore clearance. If you go too small, you risk galling the pistons when they expand enough to start dragging on the cylinders. But if you go too big, you risk excessive piston rattle. Search for a recent post I made with respect to suggested piston-bore clearances for various target horsepower levels. As for what bore size to use, I typically tell people to take it up to 88mm as it will offer a small advantage to performance. Wiseco's come with the rings. You can request for the lighter wristpins though - there is a difference of 115grams vs. 85grams for the "tapered bore" wristpins. I am using a set of the tapered bore pins in my current build, with some custom wiseco pistons I had cut out some time ago. I know the Wiseco's have the anti-detonation grooves in the top land - not sure on the others though. Stock rods are fine to use - just be sure to have them checked for roundness and clip/rehone them if necessary.
