I like em....they're on my daily driver..the ride is excellent, I've got them valved independently from one another and am running a front sway bar.....just do it right...whatever you choose....
make sure the bag isn't touching anything....make sure the lines are routed safely and use grommets where they go through metal.....get any leaks taken care of...and you should have a really nice experience with them....
I've done bags both ways, I've bought kits from Air Ride Technologies...and I've also pieced together my own suspension....so it just depends what you want to go with...or if you can fabricate some of your own stuff you can save a little $$
also, get your front end aligned where you will drive it, at ride height...or you will chew up tires fast...
