In some non IRS applications it okay to just bang thru the gears clutch in clutch out..with this vehicle you want to feather it through first gear..if you feel wheel hop..get out of the throttle a little bit more until out of 1st..you will get the hang of it after about 5 passes..long story short "wheel-hop" in an IRS application can be a driver work around.

If you dead hook you're NOT going to hop. That's the definition of dead hook. Also, hooking is the only way you're going to pull good short times.
OP, the only thing I know about wheel hop comes from owning two GTOs, which are notorious for hopping. Wheel hop is part traction, part harmonics. It starts at the very edge of losing traction, hence the hop-skip-hop-skip. However, seeing as it's all rotating at the same time, harmonics makes it worse as you lay into the throttle and spin the wheels faster. GM tried to combat this with staggered diameter half shafts. It has seen decent success on the street, less so on the strip. I've seen ZR1s hop their way through 1st and 2nd enough times to know that it's not a complete solution, at least from the factory.
There are a number of things people have tried with varying degrees of success.
Drag radials.
Stiffer springs and shocks.
GMs staggered half shaft solution - a few GTO guys have tried a version of this. They've used G-Force axles, which are the same diameter but are heavier with heavier CV cages on one side only. Apparently it works great in the dry, not so much in the wet, but fine at the track for bolt-on applications.
It's been claimed that the rear suspension has been tested to "600hp", but there's a difference between laying down some rubber at stoplights with 600hp and trying to cut 1.6 60' with 600hp. I highly doubt GM did the latter, if at all, and THAT is what is going to break shit.
