PROTOSTAR and TRINITY

I bought a PROTOSTAR and i was amazed while im playing it. after a month i want to bought a metal yoyo and it was TRINITY. The SPIN of the PROTOSTAR is more longer than the TRINITY… How come that the PROTOSTAR SPINS like that ? are there mods that i can do in my TRINITY ??

Clean the bearing on the Trinity or switch the bearings out.
