I'll second Arthur P on that one. Don't, under any circumstances, put the rest in front of the riser. While it technically may work, I have a hard time believing that it will tune properly. Not to mention that any little flinch will send the arrow WAY off course.

If you are set on using the WB, it's time to look around and change something such as purchase shorter fletchings. If nothing else can change, time to look for a new rest.

As far as 6ptsika suggested, the fletching can be in the biscuit if you want. But drawing feathers backward through the WB will really mess up the feathers!!!
