I used to own an RA and was pretty happy with it, but sold it because it's not well balanced for shooting in fresh water- too muzzle heavy. I'm sure it would work excellent in saltwater, just got to be too tiring after 6-8 hours of spearing in freshwater.
Mid-handles work better in freshwater- balance better and easier to maneuverer in limited vis and weeds. Something like a Riffe MT0 would work great. Of course, now I'm hooked on Hawaiian slings but that's another story.
