Do your homework! There is a relatively small range of spring-rates that will offer the ride quality you are looking for (whatever it might be.) The less travel you have the stiffer the spring-rate should be. Stiff shocks do not adequately counteract short travel circustances. The springs are what hold the vehicle off of the ground.
The double convoluted bag was designed to be used in a leveraged system. If you plug a double convoluted bag with no pressure in it, you will play hell trying to colapse it by hand. They have, by design, a high spring rate. That is why not many people complain about the ride of the front end (only lift issues.) So if you are going to use the double convoluted bag on the rear, build a system that will allow it to be mounted under leverage. If you need to build a simple system and cannot mount the bag as such, use a BIG bag or a sleeve style bag. The sleeve bags were designed to do exactly that.
Hearing people say that they like the way there truck rides with the bags on the axle, is like someone braging about how they like the way their Gonasyphaheralitus makes there penis feel when they pee. You get used to it. Just like bdroppeddak
said about forgetting how their trucks rode before.
Once again, I mean no disrespect to any of you, but this is something that I have done a LOT of research on.
