Well here is my 2 cents on the matter. I don't care if it is a 5" BH vs a 8" BH, out of a Hooter Shooter you will see zero difference. Can a short BH bow be shot as accurate as a long BH bow? Absolutely, can I do it......nope! As soon as I get under 6.5" my groups open up at longer ranges, heck even at 20yds shooting a Vegas face they do. Hence the reason I chase an elusive 300 on a Vegas Face with my hunting rigs. They normally sit between 7.25" and 6.5" BH with a light burner arrow and I always seem to slip up with my form on a shot or two. Last 6" BH bow I had I think my top Vegas score was a 293, compared to a 298 GT500, and a 299 with the Answer and I haven't shot my new bow for a score to know where it falls yet. I think the main reason I suffer under 6.5" is because of my DL(30.25") there is a heck of a lot less margin for error than an archer with 27"DL. JMO
As for recommendations they are just that.....try em all experiment find what works best for YOU. If someone asks for mine from my experience and trials I would advise 6.5 and above. Is that wrong or bad advice? Nope, just my honest opinion.
