Quick question for the ones using FOB's. I understand you can't/shouldn't shoot group with FOB's. I can understand why. but I do shoot groups with family sometimes. So does anyone use FOB's and blazers/vanes? on the same bow. if so do you have any problems with sights? I am not talking about long distances. I am talking about 20 maybe 30 yard shots. I am asking because I just got a few FOB's today and I like them but I enjoy shooting groups with mt cousin and uncle.
