I don't have any Ariens experience.
I do however have a 2 stage track drive snow launcher myself. 2 speed FWD 1 rev. Even this wet mushy stuff we got the other day I can launch the yuck about 30'. Even when these other guys (neighbors) bring out their "monster" snowpukers they get from the local Home depots and lowes and it barely trickles out the nozzle and gets blocked up. Get a real machine and enjoy the power. Not sure 2.7HP is going to give you that, but will do better than a single stage in most cases.
It's like asking a guy with a blown 572 cu in if your 327 needs more power.
