I'm at a bit of am impass here...
My deadlift has increased steadily since I brought it into my training a few months back.
But my wrists are killing me. My grip is tired all week afterwards, and I'm getting a bit of aching as well.
I'm concerned about bringing in the straps because I feel like I'll be building an imbalance between my back/legs and my grip.
But, OTOH, if I brought in the straps I could deadlift about a third more than I'm doing, and my wrists probably wouldn't ache all week.
I've read that you can train grip, but my grip is so annihilated from the deadlifting that I feel like I need the full week to recover. I'd trained forearms with wrist-curls for almost a year prior to starting deadlifts, and it still wasn't enough to prevent problems in that area.
