I understand that you have to use feathers if you shoot off the shelf, but the bow I was given(Bear Bearcat about 40 years old) has this little plastic rest on it, can I use vanes with this rest? Or should I just have the rest removed and shoot off the shelf? Any other advice you can give would be helpful also. I used to shoot a compound but quit a few years ago and my 7 year old got a bow for his birthday and wants dad to shoot to so I figured I would try Traditional
