OK, here is the VERY best advice you'll get, and not because it's me giving it. Go to your local pro shop and be fitted for draw length and such. Hey, while you're at it, shoot some bows and see what you like. Yes, you may indeed need a longer DL, but you may not. Only a good tech will be able to tell you for sure.

Oh, BTW, welcome to the forums! We look forward to hearing from you!!
