Put it up against mine ;)
I have had 2 1999 D2's ... First with HD coils and Lift, current with SLS and equivalent lift.
Much prefer the SLS for ride, flex, load carrying and longevity. The bags were replaced last year after what ?, 9 years of service and I expect the same out of the new bags. Show me coils that will last that long without sagging etc. And I play just about as hard as the big boys.
To cover my butt, I have 2 spare bags and a self-inflation kit that allows me to pump up the bags if the compressor or other SLS component fails with my air-pump.
