The RAD+ is a strong asymetrical design; the MB differential is 0.026 in the 15# ball, probably the highest ever in a Storm ball. The RAD+ also has a low RG, less than 2.50. The N.O.S. has a slightly higher RG (2.53) with medium flare. What really determines the dynamic is the coverstock. The Domination has the original Reactor cover, the 2Fast has the slightly stronger R2S (both pearls of course).
I had a Domination, and I felt that ball was THE best skid/flip ball Storm ever made, because they put a weaker cover on such a strong core. The transition was greatly delayed, and that ball jumped off the dry!
The R2S cover on the 2Fast will have a slightly stronger midlane and a softer backend response. The transition will be slightly earlier on the 2Fast, even though the hook potential will be much lower than the Domination.
When the T-Road Pearl and Special Agent debuted in late 2006, the description of the R2S cover was that it had a "flex additive" that widened the footprint and allowed for greater predictability, even through the standard oil transition. The R2S cover is also more durable (IMHO) than the original Reactor shell.
Hope this all helps...
