I have a previous (and lengthy) discussion of my impressions of the Nemo fins on this forum and I mainly used the Quattros prior to and currently in addition to the Nemo.

I have the same problem of the toe sticking out of the foot pocket in front and getting all messed up at the end of 30 minutes of play. Adding a lycra sock helped with the toe. Even more of a help was just taping a small peice of 3mm neoprene to the toe to protect it, but the combination of tape and the foot pocket cut off circulation to the toe and it hurts after the same time period. But at least there's no blood.

The foot pockets are still a bit too small for me (the next size up is way too big) and I may resort to heating up the foot pocket with a low powered heat gun to try to loosen them up a bit. I love the kick of the fin and just wish they fit my feet a little better.

The UW rugby fins use the same foot pocket as the UW hockey fins, so that's no help. Stick with the hockey fins. I kick a soft and meduim in the Nemos and think that through a single game I'd go witht he mediums, but the softs are just fine for about anything else except maybe extended kick sets.
