Meh, and I thought I was the one who didn't understand physics around here!
Claymore, technically you are talking about altering the balance of the weapon, eg shifting the COG ( center of gravity ) toward the pommel end. There's rather little variety in the overall weight of blades. You may want to try adding some washers between the butt end of the grip and the pommel. Triplette also makes a heavy pommel, but you will have to insulate it yourself, with Shoe Goo, Plasti-Dip, or tape. That will change the feel of the weapon. You may also want to experiment with different guard-grip-pommel combinations.
Frankly I think the canting business is snake oil. I could never feel any difference in balance with a bent tang or curved grip ( although it does seem to result in making it more necessary to make cuts with your wrist than with your fingers, as the hilt already wants to nest up in your palm ). However, I seem to be in the minority position there, so YMMV.
