RE: 3-Pin or 5-Pin Sight?
It depends on what your plans are. I just use mine for hunting and of course target shooting. I opted for the3 pin sight. I had the pins set at 10, 20, & 30, but they were all so close together it made it to cluttered. I just use 1 pin nowset at 20 yards.The difference between 20 and 30 is so small. It's probably only the width of a pin.
