The saito 100 would work, but its too light!
The 125 matches the wight of the 75ax more closely, not sure if you can move stuff forward for the cg?
Don't forget you can never have too much power
Uh, to my knowledge the Saito 100 is heavier than the 75ax; however, the Saito 100 is a little lighter than the OS 91.
