I'd probably go with an M130 still.... It's also probably a wise idea to do some mods to the gearbox so that it doesn't crack from the stress placed on it (ie. installing the "V2fix" AKA the "V2 Shock Transfer System", doing that "rounding the edges" thing to reduce shear/impact forces on the corners of the gearbox, metal torque up gears (don't know what the G&G comes stock with though), torque up motor, etc.).
