well i got two Q. and I hope they r not too stupid: 
first:The "T" in TGS stands for taps is that "zap-taps"?(which i think it is)  
second:about gear ratio..18:12 is considered like the nrml trials gear ratio,right? 
so whats the difference in pedaling(the feel) with them ratios? for instance between 18:12 and 24:18? 
Thanx.
