What piston is better Probe or Wisseco?

[Crypton2006]

I have about 20k on my probes at 500whp and still have excellent compression numbers. I daily drove the car for about 15k and am always running 20psi through a 67mm. I accidently ran 27psi on 91 octane on a couple of long highway pulls and they didnt miss a beat! I did sand down the valve relifes.

I also ran some weiscos in a dsm and had horribe piston slap when cold.

I would not hessitate to run probe if i where to do it again.

I'm running Probe's .020" over. Put down 513whp two weeks ago. Been running them for two summers and a few track passes.

Sorry to bring up an old post. I am contemplating Probe's. Can you explain this to me?
