Nothing is technically "wrong" with them but......
#1. With a prong rest you must use straight or very slightly offset fletchings. You can not use a full helical fletch and expect not to get fletching contact. i use full helical feathers.
#2. A prong rest is prone to the arrow falling off the rest when drawing the bow.To me this is unacceptable in a hunting situation. Sure it is fine on the range butI do not want to have to take my finger and put the arrow back on the rest when I am at full draw and a deer is standing there in front of me.
#3. You are always having to replace felt, teflon tubes, or some other type of prong silencing material as it wears out. And as the teflon tubes wear out they also wear down and this changes your nock high position and can change your tune slightly.
I haven't found that I spend any more time tuning a fall away rest than I do any other rest.
Thanks for your input, Bigbulls. #1 no arguement there, that's simply a statement of fact. #2 The only time I had an arrow come off the prongs while on the draw is when I was first learning to shoot a compound. Of course I was drawing too much weight. I cranked down the weight, my draw became smoother, and the arrow remained on the prongs. Sometimes I wonder if people swear by full containment rests because it hides shooting flaws like drawing back too much weight
. But, again you're right about the increased potential of the arrow falling off of the prongs in a hunting situation. #3 I put moleskin on the launcher of my drop away and it does get changed frequently.
