In MHO You shouldn't need to gear down running a 151" track.... Is it a 2" or 2.4" paddle?
The preffered helix to run (On snowest) is 66-44.46ER or the 66-42.46ER I would try that.
The biggest impovement you could make is go for a bigger track like the 159" x 2.4" or the 166" x 2.4" these tracks are rated as one of the best out there.
