Well, that sucks, I tried shooting with my left arm slightly bent, like the bow shop suggested, it felt strange, I didnt feel like I had full control of the bow, and it felt like it was more difficult to keep my arm still enough to aim for a decent shot, it feels un-natural. It sounds as though your saying the palm of my hand should be facing outward (facing you, as you view the photo)....I just stuck my hand up to my face in the manner and position your suggested, that also felt strange and un-natural.

Might be something I'll have to work on or try to get used to I guess. About what the other guy said about muscles....I hear that, my arms were a little sore the day after shooting, muscles I hadn't used or used to being sore.
