I had a mongoose in the Orion in my sig, very good IMO, wasnt the best fit though (although it was on the car when i got it), used to hang very low, but that car is now dead and the engine is in my cabby, which has a Scorpion, PERFECT fit, not sure about power as i never had any readouts done, and the scorpion has 1 less joint in the system, but i do rate the Mongoose highly.
