The Mamba Monster will give you some more top speed without changing your gearing. I don't believe that the MM is sensored, and if you want to do any slow speed crawling or climbing, you may not like it too much. Being sensorless, the motor will "cog" or jump. It will still work, but you might find it annoying. I decided my Summit was just too slow-there's just too much flat ground where I live, so I am installing a Tekin RX8/T8 sensored combo. I'll probably post in a few days and relate my experiences!
