44, do as you like, but when any of the suspensions you are considering are set up for normal riding, including occasional chop, and you encounter those deep whoops 10' apart, they are going to bottom out. The only way to prevent that would be to ride around on a very stiff suspension. All the suspensions are capable of being set up that way. That's the beauty of the ACE, you can change it on the fly and enjoy the best of both worlds. Even without the ACE, I'd go for the M-10. It really is that good. In the situation that you mention,
there is a second spring installed, called a cross over spring.
The point that spring comes into contact with the suspension
is adjustable. It's designed to dampen the bottoming out of the suspension. Instead of the sharp bang you would get with most suspensions as they bottom out, this one gets really stiff at that point, you simply don't get the sharp bang. Fast
has really got their stuff together on this suspension.
