I don't shoot a loop, wouldn't that give up more draw length?
I have no idea why my DL is short, I look pretty normal (I think). I hadit measured at a big proshop when I bought my bow, and at asmaller one later when buying arrows, both said I was 26".
I do keep a big bend in my bow arm, maybe too much?
When the room-mate gets home maybe I'll get him to snap a few pics and post them for a critique on my form.
