I don't remember what brand of grip I use, but i know the gym gives two options, one for smaller girls and one fro the older girl becaus etheir hands are bigger. I used velcro grips (non-dowel) in level four, but when i moved up to level five i got dowel leather buckle grips. I like the buckle grips a lot better because they feel more secure when doing big skills. They do not hurt your wrist becaus eof the wrist bands under them, and they wear out a lot slower than some of the velcro grip i've seen or used. I know some gyms do not require grip use before a certian level, but i think it is best t o get used to them early on with small skills, than try to use them after you get a giant or fly away. They help you grip the bar much better, and prevant blisters. The buckle (i think) also works better than velcro becasue the buckle always works, where as velcor can wear out or well, not velcro any more. Hope you foun dthis rambling reply helpful!
