Any time you change anything on your bow like arrow rest or sights or even diffrent arrows. never asume that every thing is honky dorry and is going to shoot just as it did before! Once you put the new one on shoot it threw papper just to be on the safe side. But just changing out to the b2 with the slot in it you should be fairly close as the old one!
Like RTA47 said every person's setup is going to be different but I can tell you that when I switched from the black biscuit to the new B2 about a month ago, my arrows consistently impacted about 2-3 inches higher than the old one!! So as always it's a good idea to get things back into tune and to the nuts!!!
