Sounds like you are on top of it.
I agree with you on the wrist roller. I actually think it is the best grip trainer I do, in general. I actually just use a homeade one make with a a round piece of wood with a hole drilled in it. I don't like the commercial ones because everyone I've tried has foam handles and I feel that helps me grip it too much and I want to have the grip challenged as much as possible and not just turn it into a glorified wrist curl. Next time I'll see if I can write a longer sentence than that
.
I'd say just watch you grip. If you have trouble with your deads you'll know what it's from.
