This is the key to a plusher more coil like feel because The reason you have to play with spring rates to get the best compromise
is the reason you need ramp up through the This 3 part solution is what all forks have been using for 50 years,

Typical Hybrid Coil/Air Spring Combined Forces Flattens the belly(hammock) in the air spring system for more midstroke support.
Hybrid Coil/Air vs Tokens vs Oil Height Spring Forces As you can see the tokens will change the progression thru the
middle to end of stroke.

How our customer describes this system, "Motocross forks utilize a combo of coil and air (they use oil volume to adjust air pressure progression) because it tends to work the best. You get a fork that isn't initially too soft/ divey and a well supported mid stroke due to the coil and then you get the progression needed at the end to prevent harsh bottom outs. No doubt a hydraulic bottom out works as well but then you might lose some other benefits of a hybrid setup, mainly spreading the spring force between both legs so that they work in better harmony. With all the spring force in one leg of a mountain bike fork some have reported notably different amounts of travel being used by each fork leg due to the flex." The hybrid coil kit supports about half the rider weight and the air spring makes up for the other half of the support needed. Now the air side can be used to fine tune the spring rate needed as well as adjust the ride height for different riding conditions, also the air ramp-up can be controlled with the traditional tokens or aftermarket ramp up adjustment devices. The advantage of the hybrid system is versatility, performance, weight, and cost savings. It simply drops on top of our open bath damper side, only adds about 180 grams(250 grams for 8 inch fork), it solves most of the air spring issues in the first half of the stroke, where the friction forces and small bump compliance are critical, more supportive, it fills in the midstroke wallow of the air spring and corrects the ride height with physical adjustable preload. When the fork gets deeper in the stroke the spring force is more dominant and the stiction and air spring concerns are not as noticeable, so the final spring force is not as sensitive as long as it is more linear and removal of the tokens is now possible with proper damping. The air spring can be set to very low pressures and as linear as possible where it is nearly negligible. Ride height and spring rate can be fine tuned with the air spring pressure which is very helpful when in between spring rates and allows for different riding conditions. The equal force system is a very important feature because now the fork compresses equally with about the same spring rate in both stanchions, a single spring system causes the unsprung side to compress ahead the spring side because of the flexibility of the crown and lowers, this causes stiction in the first half of the travel which is more of a contributor than the air spring stiction. The abs system that we sell as an option to our damper is not necessary because of the air hybrid ramp up is sufficient to prevent bottoming.
