I finally got around to shooting broadheads tonight after a few weeks of dealing with stuff like a broken sight and switching arrows.

I go to draw the first arrow, i hear a tink and it falls on the ground, "hmm what the heck happened there?" so i re-nock it and draw again with the same results. Seems the broadhead blade is catching on the riser or the arrow holder thingy on the shelf.
I had my wife watch me draw and it is hitting the plastic channel the shop glued to the shelf to hold the arrow (using a Trophy Ridge Drop Zone).

The tech glued it on right at the front of the riser and with the overdraw, the location of the rest and the angle of incline as the arrow s raised it just barely catches the plastic guide. I am going to take the guide off and make 100% sure it isnt going to catch the riser then i will reattach the guide further back on the shelf.

It looks like they used a very thin neoprene pad with adhesive on both sides. Would i just be able to go to Home Depot and find something similar that would do the job or would i need to drive 30 miles each way to get some special tape or glue at the shop?

Of course if the blades are catching the riser too it looks like i will be buying another set of arrows probably 1/2" to 1" longer
