I don't really see the benefits of palm grips since I'm not really even convinced they'll prevent ripping. Maybe for some. I don't see them as particularly valuable and in my experience ripping comes from a gain in height/weight or getting used to swinging bigger skills and for longer periods of time. The only period I went through that I consistently ripped was when I was a L6/7 (first two years I used grips) and we went to bars more than once a practice a lot of days We would go and then go back at the end if we had time, usually over vaulting. Worked, for the next three years I went from having very little bar skill/technique to state champion at optional levels, but the transition period was really rough and honestly I almost quit over it because I was behind already so I felt like I couldn't meet the expectations. My hands would be bleeding and I still had five more sets of skills I wasn't confident with.
BUT by the time I was a L8 I never ripped and I haven't ripped in the 5 years since. Even when I stopped swinging bars for a couple months and then went back, I expected to rip but I didn't. I switched gyms at one point, changed bar settings and workout methods and went through a huge setback on bars which had been my best....it was the only thing that really suffered but I feel like that's easy on bars for most people. It's not an event where general preparation in other areas easily transfers and coming off a several month break (I had been in really good shape before and had most of my old bar skills back prior) it was the only thing that I really couldn't get back into. Any tumbling, beam, vault problems I had were more mental than physical. On bars I found I couldn't do a long hang kip cast handstand, my rhythm was so off. If it isn't one thing it's something else. Gymnastics is a marathon and there are always going to be little setbacks and obstacles to overcome. In time you'll look back and something that seemed so agonizing at the time will just have been a little bump in the road.
