But after really trying them and seeing what they do I have to agree that they help eliminate fletching clearance----if you have fletching contact. But in the vast majority of cases fletching contact is a result of poor tuning or a lack of tuning in the first place.
This is where drop away rests shine.It is definetly true thatwith TM style rests you could easily get them to tune on your bow and could easily get great fletchig clearance
IF you shot straight or very slight offset vanes or feathers. Once you got more than about 2-3 degrees offsetwith your vanes fletching contact became a very real issue.
With a drop away rest you can use extreme amounts of helical for much better broadhead control than you ever could with a TM style rest.
I feel that is one of the myths of the drop a way rests, that they are more forgiving. The shot happens so fast, and so many things are flying all over the place that I just don't see it happening.
I'll take all I can get. The same thing could be said for bows in general. Longer ATA, longer brace height, more mass, etc... Are you going to notice the difference between a 7" brace height and a 7.5" brace height? Or a 2 inch longer ATA length. Or .2 more pounds of weight on the bow? Not likely but add them all up together and you get a more forgiving set up.
