Default Nitrous Piston Rings

Looking to pull the trigger on a set of rings today. Setup: cleaned up aluminum 347 with stock rods, pistons, crank + aftermarket cam and supporting valvetrain. Planning to start on a wet 150 and possibly work my way up to a 250 shot. What rings would be ideal for my weekend street/strip setup? I know there are a lot of people running OEM, and I have looked into the Hellfires, but they seem to be overkill. What's recommended that fall's in between? These Sealed Power E938K's seem to be fairly reasonable:

"If you're going to spray alot, the kind piston is going to matter a little more compared to what the ring is made of.

A piston with the ring down further in the bore with more meat on the ringlands to me is more of an issue. Plus having a good compression height

A good ring on a not-so-good of a piston choice is a worse situation than a mediocre ring on a good piston."

Do most concur with this statement?

Reason for running thicker rings is to make the pistons more tolerable of a bad tune up. If you have a thin ring land and you run your nitrous tune too rich, you'll get unburnt fuel and nitrous in the top ring and when it does ignite it will lift the ringland and lock up the rings.
It can still happen with forged pistons as well but they are just more tolerable and if you run stock pistons your tune needs to be dead on.. I'd rather have a lean tune up than a rich tune up..
