Piston Ring Preferences?

I am building a Pontiac 455 engine with about 12:1 compression and I'm wanting to run Nitrous for about 100 or 150hp shot, MAX. I've read up on this a little bit and it seems to me that a lot of people prefer Hellfire rings for all out racing. Yet others seem to prefer Plasma Moly rings, do I really need to use the Hellfire rings on a street rod or are Plasma rings enough for me? If someone could help me out that would be awesome, I'm pretty new to the NOS game and I would appreciate suggestions on this.
Thanks Dylan

rings

I have run the good old plane moly rings in a few customer engines with 100/200 plates with zero issues.

At the 100 level it's almost impossible to do damage, It can still happen but you really need to make a big mistake. Getting to the 200 level you can then start to burn things up if you are not good at the tune. The hell fire rings might offer some resistance to this mistake at the 200 level, but other parts are not going to be so lucky. So since your going to break things anyway if something goes wrong, having a cherry set of rings hanging on a piston with the top ring land lifted is going to be useless..

Unless you hitting it with 3 kits you really do-not need the hell fire rings.
