I think you'd find that it is a worthy tournament bow, due to it's length and stability. It also has the tallest sight window of the Widow recurves, which makes it the best option for those who would shoot with sights.
But if you don't mind the length -- I don't, as I shoot a 64" PMA myself -- then the things that make it a great tournament bow would also be positives for hunting. Jack Howard hunted with 66" recurves and is one of the great bowhunters of our recent past. The only reason for considering a PSA (2-inch shorter riser) or a PCH (4-inch shorter riser, I think) would be to get it in and out of tighter shooting situations. And... I guess some people just like shorter bows.
I've shot Widows as short as 56", and personally prefer the stability of the 64" PMA over all the others. That being said, I may end up adding a PCH or a PSR to my bow collection, to have a "short bow" if I feel that I need it.
If you want to cut to the chase on this topic, call Black Widow and ask Roger or Toby. They are easy to talk to and know more about their bows than anyone else. Great company, great bows, great people.
