My only issue with the Saito is the fuel draw. If you put the tank back at the CG, put a Cline regulator on it or go with the YS. IMO, the YS is more of a powerhouse than the Saito. It also weighs 5 - 6oz more. It ends up that you should choose what you are comfortable with. There is no real price difference, but I think that you still have to add the Cline for the Saito. I have a YS 120 on mine because I fly at 5200' otherwise I would have used the YS 91.
