Either will work great and keep the nose down. Its all how its mounted, that iss the most critical part. 1/4'' makes a HUGE difference in the ride quality big time. IF its set up perfect you will love either one, if its in there halfass it will ride like a concrete truck of ride like a wet noodle. M-10's are just like turbo kits, its only as good as the person that installs it. And there the only skid i would ever put in an Apex, for whaterver reason the Apex chassis loves the M-10. The Nytro, im not so sure about because its such a weight and rider forward machine, time will tell once its set up and adjusted perfect.
