MAN UP! The pain factor is pretty much the same for both.
If your truly concerned, find yourself a full head coverage mask, some thick BDUs, knee pads, elbow pads, neck guard... The most painful in my opinion is getting hit in the nails or knuckles, so a good pair of gloves would be a plus. Oh yea, ball shots would probably hurt too, I had no serious ballsack injuries and I try not to think about it LOL
