Like I said, it seems pretty new in gymnastics marketing. I had never heard about it. I just went to the website and it indeed says "new" before the description. I can't really say for sure. But I can say that the Tac-10 material (basketball looking) vaults and springboards were originally marketed and believed to be non-skid, would not become slick as fast. But truthfully they will eventually get the non-skid covering worn down after heavy use. So I am not sure. Gymnasts put most things through heavy friction use and while I can imagine these might slip less the first couple months compared to regular ones, I do think you'll be replacing them fairly frequently to maintain those properties. It won't be a one time purchase in other words. And it's not just slipping, I do find it harder to grip the beam the way I would prefer with the design of Tiger Paws.
Don't get me wrong, I think EVERY gymnast should be using them for yurchenkos, and many for tumbling too. In particular you said in another thread your daughter has a weak bridge and possible shoulder and hip flexor tightness, this could be putting even more strain on her wrists, so I would definitely advise for floor and vault ASAP. For beam, maybe it will be okay for her, maybe not. It's a pretty individual thing, I can tell you a few high level gymnasts use them on this event, and in my experience, more do not. But I obviously haven't run a large scale study on that, could be wrong. In the sense that I think your daughter will probably need them, in addition to exercises to target increasingly flexibility and strength in the wrists, I don't think it would be a wasted purchase...you just might need another solution for beam.
