Thanks Jeffrevs. I know the differences in the core design, anybody can look at the differential, the rg, the spin time, and the mb differential. These differences are obvious as is the oob surface prep. I happen to have an S&D and love it.
The covers are the grey area. Other than what the company says about the cover, pearl/solid, particle loads, and hardness, there is no real universal characterization. Other than throwing, lets say, the xxxcel and the TS&A one cannot differentiate between the covers. In one company, especially if you are experienced with that company, one can guestimate, rather accuratly, the differences in cover as to the spot at which the cover reads the lane, and how well it hooks in oil/dry.
One more thing, does anyone know how the C4 enhanced pk 18 is different in the TS&A and the TA? Does the TS&A have a stronger cover? Also what load of particle is the WMB and/or the S&D?
