The horse ain't dead yet
I think he even said that he has two sets of sights that he interchanges for tips, and broadheads. UNREAL.
I don't see a problem with this.............I have done it many times. IMO probably the best way to do it.
Of course I am a little lazier now a days so I just tune the bh's to my field points and call it good.
But when I had the time and space to really group tune my Bh's - I always used another sight or moved the one I had.
