High compression pistons?

Speedpro makes a nice set of lightweight forged pistons that with a set of trickflo heads run right at 11:1 CR, if youre willing to break from the "its gotta be forged" crowd, KB makes a Hyperutectic piston that also hits the 11:1 range that is the sister to the ones I am using in my 429CJ with alum heads, etc (DD est 550Hp) and I have no complaints about them at all (I've ran a set of KB Hypers in my Harley for the past 3 yrs now.... dynoed at 100Hp, 10.5:1 CR and ridden all over the place... plus a race or two ;-) )
