I'd considered that, but I figured that it'd be cheaper to go for the sprocket option (I'm a student, so, zero disposable income =P) plus while you're right about the fine tuning option, it would mean possibly more trial and error trying the different sizes, i've bought myself a 15t there so hopefully that'll do the trick. Thanks anyway, all responses are greatly appreciated =D
