The Blackhawk is a fairly new model, and doesn't seem to have any reviews yet. But it seems similar to the Ultimate, which Friend and I have, maybe with a few less bells and whistles. The Bob Lee design has been proven over many years and 3 generations of the Lee family. Like Wheels said, the fit of a bow is very personal, and what one person loves another person might hate. That said, the Bob Lee standard grip is probably loved by more people than any other standard grip in history, so the odds are pretty good that you'll like it.
If this bow is anything like the Ultimate or the Heavyweight, it is a Heavy bow! This of course is good for shooting stability, but some people would prefer a lighter mass weight bow. Keep that in mind. Another thing to keep in mind is whether you really want to pay $300 or so extra for the Stabi-lock. I have one on my Ultimate, and it works fine, but to be honest I have never had it apart other than to learn to use it and once in a while to make sure it hasn't stuck together. The basic Bob Lee two bolt attachment system is one of the best there is. I have it on several other Bob Lee's I have, and really could wish for nothing more.
The Ultimate will probably be my go to hunting bow for the rest of my life, given my age. I have several other bows that would work just as well, but they are too fancy and I would hate to get them scratched, whereas a scratch on the Ultimate would just give it some character.
