Can you tell me your experience with the airbags? I am still on the fence if I should buy a custom leaf pack, or go helper air bags. My main concern with air bags is limited suspension articulation, and reliability. I don't want to sacrifice articulation in any way, and I also don't want a bag failure out deep on a trail somewhere. As of now, I am leaning towards a custom leaf pack for reliability.
Weight and reliability are huge concerns for me during this whole upcoming build (being in racing my whole professional career, it is ingrained in everything we do). I know the negative handling effects of having a high spring rate in the rear of the vehicle while leaving the front close to stock rate, especially without anti-roll bars hooked up. I am going to try to minimize the amount of additional weight added to the rear of the vehicle, and try to even the weight from front to rear. My hope is that I can move up spring rates equally (or as close as possible) front and rear to negate any odd handling woes. After our trip is over, I figured I could always switch back to my current spring set up to make day to day driving easier.
I wish I had more info for you, but mine just showed up via UPS a day ago.
I spent some time digging around as I was making the same decision you are. After a couple trips this summer, I realized Xterra squat is definitely a thing, and it needed addressing...especially when pulling the trailer. I didn't want to go with different leafs because most of the time the thing isn't loaded down, and I don't want to sacrifice ride. I found a thread on thenewX.org (I think) where the guy was installing the Firestone bags, and he showed the wheel unweighted and the bag was not stretched to it's end, meaning that (I think...I'm definitely not an expert) I should have full (or almost full) articulation if the bags are deflated.
Plus, if you have a bag failure, you just deflate the other one and you basically still have stock suspension.
I'm sure I'm going to give up a little off road, but the X can do things way beyond my off road capabilities already (I accidentally found this out this summer in CO...the X totally made me look like a hero on a trail I had no place being on), so I think it'll be okay. Plus, I'm not sure if you would maintain articulation with a new leaf pack, anyway would you? I really don't know.
