nhyrum,

I think the riser will help a lot. It may help to have any different angle to give you a break from the original motion.

Pick up an anti-fatigue mat to stand on while you are at it. If your feet get tired you tend to automatically lean at odd angles to relieve the pressure on them.

If you get a 650, get auto case and bullet feeders so you can operate it with one hand. That will let you switch off right and left from time to time.
