I have a 200 and just use third as well as second to give me longer gearing when required. I hardly ever use 1st....
Trials gearing is not a set sequence i.e. 1,2,3,4,5 & 6 once flat out. You often start off in say 2nd or third gear and thats it unless on the road/trail. 200's always run out of puff on this kind of going though.
