That's weird because i joined 24 hour just last week and was thinking exactly the same thing just yesterday about the lat bars while doing back, decided i'd ask someone. Because all their gyms seem to have the same bars, I have a feeling they're all ordered in bulk thru one channel of the company, which probably means it's not easy to get something that's out of the norm. I'm going to talk to someone today after my workout and find out. It depends on the chain, at LA Fitness where i was previously, there was more variation in equipment from gym to gym, which told me they have more latitude to get something different.
I like their hex plates.
The other thing they're missing at least in my gym is a pullover machine. Other than that they have a good selection and i like the layout and energy better than LA Fitness.
