I don't use chalk or straps to dead. I may use chalk occasionally for reps but i don't really need it. As for straps, i use them on shrugs if i ever do them, and rack deads and SLDL's. I hate doing racks and Stiff legs with an over under grip, so the only other option is straps. As far as the other bullshit back work, i don't think i have ever even come close to losing my grip. I think if you need grip for what you do, not using straps is good, due to the amount of volume you get. As far as bodybuilding goes, i think if you have massive forearms do whatever, if you don't, maybe you should look at the fact that you are using straps for everything. Like verything else, their is no cut and dry answer.
