I do what gibblet says and it works great. I have my girlfriened doing this before every round of arrows because she changes her stance all the time.

As far draw length the best way would be to find pictures, look at them and compare them to how you look. Have someone take some pics of you at full draw and you can post them. If I remember and have time this week maybe I will try and find some on different sites and link you to them. There are probably some on this one. Search for a thread called something like "show yourself at full draw" or something like that. It's a few pages back on the bowhunting forum. Several pages with plenty of pics and critiques I bet. I may post some of me and my girl so it will come to the top again.

Bottom line, if you don't feel comfortable with it, have the shop change it. When first setting up a bow it is just a best guess, not a final measurement. They should not even charge you anything if you got the bow there to begin with. I'm not saying that for sure, depends on the shop. The place where I got mine caters to it's costomers in that respect. Just go in and tell them it doesn't feel right and you want to try a shorter draw length. I have three bows and none of them have the same exact draw length. Each bow and set up will feel slightly different and needs to be tweaked. I'm between 25 and 26 inches most of the time though with a wrist release.
