This depends on several factors. If you are a serious lifter who is in the gym multiple days each week, we recommend that you order the Xtreme or Pro. If you have smaller hands and are looking for a more slimmed-down product, we recommend the Fit. If you are new to weightlifting, or just want to try Versa Gripps out at a lower price, Classic Versa Gripps are a perfect entry-level product.
