I use the swivel regardless of the leg style, and use a US Optics level that mounts on the rail to insure that the rifle is level for every shot. Also installed Terry Cross Pod Loc on every Harris bipod. Topped the rifles with the US Optics level that mounts on the rail.
I do not attempt to duplicate the initial rifle position when shooting prone on loose bare dirt since after a few shots it's virtually impossible as the bipod digs into the dirt, but rather make sure that I'm level and have the same hold.
Some will argure on technique, but technique is really an individual choice to compensate for differences in equipment and physique. All that really matters it what the target looks like at the end of a string.
