Just a few thoughts.
An HP100 is about 15 pounds lighter out of the water than an LP104. It also is slightly more streamline in the water. They have about the same buoyancy characterists. Most boats and some shops can't fill to 3500 psi so on your second boat dive you may end up with 2700 psi which is about 77 cuft. This isn't all that bad considering you should have a minimum equivalency of an AL80 for the second dive while still taking 5 pounds off your weight harness.
