Let's see...
I, for one, think that your back workouts should suffer because of a weak grip. Your back workout should be finished once your forearms have become fatigued... yeah, that works.
Grip get stronger very fast if you don't use straps all the time. And how many of you guys use more than 1.5 x body weight for pull-downs and rows? If you need straps while doing chins without any extra plates, you really need stronger grip more than straps.
And how about a lifting belt? How many of you guys wear it all the time from the locker room, during all exercises and take it of just for the shower? I use lifting belt for 0 exercises, because I have realize long time a go that I need strong lower back more than some freaking belt to support my lifts. Using the belt means that you don't use your muscles to support your body and your middle section grows weaker. I know a bunch of lifters who has problems with their lower back and who try to help it heal by wearing lifting belt which is wrong way to do it. You get lower back problems at the first place by wearing belt, and you can get rid of them only by training your middle section and make it strong enough for the sport. For example, I do crunhes and hyperextensions every time I go to gym, it is a great way to warm up. 3 to 5 sets of 20 reps depending what I'am going to do. 3 sets, If training chest and arms, 4 sets if training legs and five sets if training back and shouders.
