I think that I read somewhere that the mixed grip, when not varied between arms, can actually cause spinal imbalances. I don't know if that's true, but I prefer not to find out.
I use the hook grip, since I don't deadlift really heavy any more. Up to 365, no problems with it.
I think I read that the pronated arm's lateral biceps head is stretched more than on the supinated arm. The theory was that later when you lift heavy and change your grip, the lat head of the biceps on the arm that you usually supinate can rupture. It sounded far-fetched to me.
I also use hook grip. I don't lift as heavy as many guys do, but I can grip more weight with a hook grip than I can with alternate grip. I haven't used straps since I started using the hook grip.
Saw a guy in a Gold's Gym yesterday DLing 405 with a rounded back and a strange set-up. He knelt in front of the bar while he adjusted his straps, then stood up and pulled. My son later saw him using straps on several machines. Pretty strong to lift that way. Imagine what he could do with good form.
