I have used both on elk, deer, and antelope.......have chipped and broke bleeders on both, and can group good out to 115 yds with both, honestly everything I've shot with them the thing you have to worry about it finding your dang arrow after they pass thru both heads seem to not even slow down...
I was also having the same problem over and over i've swapped top hats a million times and was this close to getting rid of the bow, I moved my rest back towards me about .25 to .5" and it seemed to clean alot of it up...still working it out but that seemed to help more than moving my top hats...
