I shoot 3 pin, but I' ve thought of the single pin, just didn' t have enough time to practice before season started. I have those one' s that are supposed to suck up all available light and be good till the last drop of light is gone. They work pretty well so far as I' ve been able to tell. If I went to single pin I' d go for the same type of pin, or I could just take out the extra 2 that I have now. The green and yellow are the easiest to see late at night, the red is not so good. The yellow, however, is even better than the green.
