The equipment does help some, I know from personal experience that the MPC wheels help (indoor) my lap time improved the second I got on them. I didn't try the MPC outdoor at Road Rash because I just didn't have the cash for MPC's, plus I didn't know what to get. I say its about 10-15% equipment 85-90% the skater.
I have to ask you though Jimmy, Do you only skate on the 100's because the 110's have TOO much meat on them or what?
