Super springs vs. custom springs

I've been running air bags on my last 2 trucks for carrying my camper. I currently have them on my '05 Chevy dually. They've worked pretty well but I'm always chasing leaks it seems. Lately as soon as I fix one leak 2 more develop.
I've had it with the bags. I was looking at Supper Springs but I'm really skeptical. I've got 8 leaves under each side now and that's not enough. 1 more is supposed to make all the difference?
The rig weighs in about 13,100 ready to camp. I carry almost 9,000 pounds on the rear axle. I'm thinking that having a spring shop make some custom springs would be a good way to go. Who has had that done? How much did it cost? Were you happy with the results? How is the unloaded ride?

Thanks for the help.
