With the thinner string the diabolo spins alot faster on the string but with the thick string there is less cahnce of rips
Try taking a look at your diabolo's axleIf you see it's not that shiny then give it a polish i recommend shoe lace because it works amazingly good
although i'm also noticing 1 advantage to the nice pattern on the arlequins: you can see how fast your diabolo is still turning :pbut i'll get a feel of the new diabolos too probably
also a little update from me: ... bought me some good aluminium diabolo sticks... , some good rope (henry's yellow), and 2 henry's circus diabolos ... i must say i very much feel the difference....
