Icon FHR IC9977 pistons
FWIW, I have used hypers in turbo rally cars for a few thousand full-bore rally miles, with 14-15 psi boost. Absolutely no problems.
The idea that there is a reliability problem with hypers is not correct. Forged are 'tougher' (in the materials science sense of the word) and will take more ABUSE with excess heat, extended pounding, and detonation, but hypers are strong and do just fine for most everyone's needs. Plus they are considerably lighter, and thus take stress off of the crank and rods at high RPM's.
The tighter piston-to-wall clearance of hypers will tend to work better on the street if you are doing a lot of long distance cruising or just street driving. So it also depends on the use.
