For a superior grip when lifting, "hooking" is the way to go. It may take a few weeks to get used to it, but once you've broken it in, there is will be no turning back. Just grip the bar with your fingers over your thumb. Although used mostly by Olympic lifters, hooking can also be very beneficial for deadlifters. By holding your DL's this way with both hands pronated with the palms back, your chances of biceps injuries will be minimual.
Don't use the excuse, "my hands are too small". If Precious McKenzie can hook grip his DL's, anyone can.
