RE: TR DropZone Setup Help Needed
The foam guide looks like garbage, but it's really useful when you put it on. One tip here, put the foam piece as far forward on the riser as possible, toward the front of the bow.
Use a brass nock to help set the chord on your lower cable. Set it so that the launcher arm comes into contact with the shaft at a point between 2/3 and 3/4 of the way to the tip of the arrow. Once you have the position, then serve it in. I just burned a mushroom on the end of the chord, then ran it through the center of the cable. This keeps it from slipping through the cable, and the brass nock keeps it from moving up upon the draw. Again, replace the nock with serving once your position is set.
As far as the mounting hole you use, I think it's a matter of personal preference. Mine is attached so that the rest is closest to the riser.
