Ahem... dare I say 2d vertax? It would be the wrap start but both diabolos would be spinning relatively fast. It also adds another dimension to knots.Beni(I want what I can't have )

Hey, i just thought about this, but if you took a rev kit and put it into vertax, you could just place it on your palm like a stagnant top. That'd be an awesome stall, and you could whip it off your hand XD

There has to be some integrals akin to cracker's 2d integral start.

a slightly longer axle and my one will fit a circus, all you need is the fixings for a finnesse. this can be arranged for the same sum.lzhehehe
