I was wondering ,the difference between phenolic tips and a g-10 tip ? My break jump cue has a phenolic tip and it breaks and jumps ok. But a guy a started playing with has a g-10 tip on his cue and he sys they are better and make jumping easier , i was wondering if i could get some opinions on them ? And also someone else said the g-10 is illegal in some leagues or tournaments ? Thanks in advance !!
