I would go with OEM pistons. You have single ring pistons I believe. I like dual ring pistons which is what the 2007 Polaris 700 engines came with so that would be my preference. OEM are cast pistons. Personally I have only replaced pistons due to high mileage once ( probably unnecessarily as they looked to be in excellent condition) and I replaced them with stock pistons from Polaris. Forged pistons like Wisecos are cheaper than OEM but I like the durability of stock. Here is a link to a post by IndyDan of Indy Specialty regarding piston replacement albeit regarding the 800 motors but I think the same logic applies to any engine. IndyDan post

Have you had a chance to figure out why the pto side went down? Leaking crank seal?

I haven’t had the chance to tear the engine apart only checked for the compression

What I think happened was it got too hot, crank seal was good, the past owner I got it from prob didn’t properly add coolant like the first time I changed the piston, but learned after watching YouTube videos on adding coolant after engine rebuild
