Big Eon...the guy is pumped about his new bow and you have to post some junk because he didn't pick a Browning...geesh...
wholelottagobble...congrats on the new bow, welcome to a great sport! Sounds like the guy at the shop had your best interest in mind instead of just trying to sell you a high dollar bow. The longer ATA will help you and will be more forgiving while you are trying to find your form. While I have not shot an HCA bow, in this day and age it is rare that you find many lemon bows...
Good luck, have fun and ask lots of questions! Best of luck this fall!!
