Using an "accumulator" or additional 1/2-1 gallon air tank at each corner will give the air somewhere to compress to when you hit a bump, but the obvious downside is that it uses A LOT more air to go up because you have to fill the accumulator, too.
Cylinders ride rough because they can't expand out like a bag can when you hit a bump. If you want to try to soften the front end a bit, move your valves to the trunk so you have all of that air line for expansion- some people find that it's enough of an improvement to live with. Good luck!
