Poxy, i have both and like them a lot. the only thing is, that i have a different drilling in each one. the bw is a 90* layout with a 4 1/2"pin above fingers and this ball reads the midlanes great. i can either circle the pattern or can go down the boards to give it a little more pop in the back. the total nv has one of those trick layouts to where the ball really gets down lane and makes a strong roll(not flip)off the breakpoint. obviously if there is heavy oil, the total nv is probably going to go way too long for me. it really all depends on if you want a ball for medium/heavy or just medium. you can tweak the surface on each ball, but then if you put a surface on the total nv, you will be getting a ball that wants to read a little sooner. hope this helps.
BenDover, if you are looking for something to replace your infinite one, then i would probably go with a no mercy. i have never thrown one, but hear it is a decent ball. you can tweak the surface so that it can read either a little sooner or a little later. IMO, the angular one and total nv may go too long in the heavier patterns and such. good luck to the both of you...
