It's hard to not find a good piston these days. Wiseco is kinda "old school" and not really in the limelight anymore, but I'm sure they still make a good product. They are pioneers.

I mainly use Diamond and Racetec. I can get fully custom Racetec pistons, in any bore size (.001" increments), volume, ring pack, etc., for not much more than a regular off-the-shelf forged piston.

I see a lot of pistons still offering their slugs with 1/16, 3/16 ring pack dimensions and those are far from being "current". Most of my street pistons use a 1.5/1.5/3mm ring pack and my racier stuff uses 1/1/2mm packs.

I agree with the other guys....no reason to keep the compression up. The horsepower difference between 10:1 and 11:1 is negligible, but your pistons will thank you when you get a snoot full of bad pump gas.

If that one were mine, I'd run 9.5-10:1.
