I use Jetfins, and I always dive dry. I did have to distribute my weight to account for their negativity, however, I am not adding weight beyond what I need for buoyancy issues. So, I don't have a need at this point for lighter fins. My trim is quite good if I do say so myself.
I have heard good things about the Dive Rite fins. I have never tried them, but a friend of mine rented a set to try them out. While he had positive things to say, it is not like he is now using those instead of his Jets.
I have never tried or really seen the OMS on the water.
