RE: Some Newbie Questions
Welcome to bowhunting!
1. If you are shooting a release you shouldn' t have a problem with the arrow falling off the rest, unless your pulling too much weight causing you to jerk. As far as drop aways, I use one but I don' t think I would recommend one to a new bowhunter. Look into Golden Key and Bodoodle, they make great arrow rests. I can' t speak for the wisker bisquit, but have heard it has problems with freezing up.
2. For sights, I would stick with fixed pins at first, I use a trophy ridge and love it, but there are many other pin sights that are very good. Really, I think you looking a personal preference here.
3. Draw weight is also personal preference. You will have a flatter shooting bow with more weight, but in my opinion the difference is relatively minor. 50-60 is plenty of weight to kill any animal.
4. Axle to Axle lenght on bows is also relatively null, unless your talking about the difference between a 30 inch and 40 inch. Choose something in between and you' ll be fine.
Good luck, hope this helps.
