Ok, Scott, you knew I was going to chime in here somewhere; so, here's goes the long winded, somewhat detailed schpiel.
I use(d) my New Standard for medium to medium-heavy oil of all lengths. My Yeah Baby! is 5 - 10 boards stronger than my NS with the same drill. So, if I ever see TRUE heavy oil, I almost certain I can find a line somewhere with the YB.
Back when it came out, the YB used the diamond particles and was spec'd by Legends to be a heavy load, yet it got better than average length for such an oil loving ball, possibly due to its core. When the Terminator came out, it used a special combination of large and small particles, not available with the diamonds. So I assumed Lanemasters used their "super carbon" particles. While I don't like the idea that they polish the Terminator, for most people on most conditions, this seems to be required, because it is an early grabbing coverstock formulation. The YB! seems to go longer than the Term, but has more backend, in general. The YB has a large amount of hook and a large amount of backend for the average rev bowler, who has average ball speed on true medium-heavy oil patterns, IN MY OPINION.
With respect to the NS2, it also has a heavy load of Diamond particles but is meant to be more of a control ball than the NS. It needs as much oil in the heads as the NS and the YB AND the Term. If you add some polish, the NS2, with its high flare and particles becomes a devastating large hook, medium to medium-heavy all ball, kind of equivalent to but not exactly like the YB. It can be a spookily strong ball when you smooth out the rough stock surface.
Like the YB, the NS2 needs to have somewhere near the stock surface, otherwise it becomes almost a particle skid/flip reaction, which is not what most people think of with particle balls.
So, depending on how you drill the YB with respect to the NS2, it could fit differently. With their stock surfaces, and similar drills, the YB should fit 1/4 - 1/2 a notch above the NS2 in oil handling and in overall hook, with more length and more backend.
(If some notes in different paragraphs, don't jive, it oculd be my sipping the Sauternes between typing and cooking Thanksgiving dinner. Yes, I'm a man of many talents and no skills ...
The artichokes and the stuffing await my imminent return. So if post any goofs I made and I'll get back to you.)
