I rather shaft but I am from 1/8 buggy background. I have seen my friends work on his belt drive car (v1s), It looked much more complex then working on shaft drive! But can't say Ive taken much notice of others working on their belt drive cars..
S.Stew, apparently from what I read on the "belt Vs shaft" threads, there is more lag in belt.
The lag from "gap" in the gears you are talking about
? that would be comparable to the "lag" from the slight slop you have in new drive cups..
also from what others have said , as shaft is more responsive it requires different throttle input to belt car (different drive style?) You need to speak to someone who has driven and got used to both cars! not just tried one and didnt like it (ie gave up before learning)
I have 0.8 gearing ordered for my LD3 woohoo
