ditto. I don't have great numbers, my bench is terrible, not even 1.5x BW, but I did manage to get my DL to ~2.5x in a competition, then tweaked my back and now only double overhand, which means my grip tends to go when I get to ~2x BW (my gym doesn't allow chalk, and I don't use straps, so it is what it is).
Do you mind if I ask what you did which restricts your ability to mixed grip? In terms of loading, I would expect your back to be loaded in a similar manner irrespective of the hand position.
Not who you asked but I use overhand hook grip and do conventional deadlifts (not sumo). I find mixed grip bothers my bicep on the underhand side. I also use chalk, and straps for heavy pulls.
I don't understand a gym that doesn't allow chalk.
somehow mixed grip makes me twist slightly which caused me back problems; after a few tweaks to the lower back, I decided that mixed wasn't worth it (I don't compete anymore). Yes, you are right, I do use the hook grip, since I also do some weightlifting.
