Need help with air bag options

[stacerbob]

I was getting ready to order some drop springs for my blazer & got to looking, I can do air bags for not much more $$$. What bags do you experts recommend? 2600# front & 2500# rear? Should I spend more & get the heavier duty/ reinforced ones? Which brand is better & still economical? I am looking on suicide doors & the airlift 2b7 & 2b6 they say 300psi & are 1/2" dual port. Is that a good choice? They have cheaper than that & of course higher. I can't afford the compressor & such right now. But do I NEED the dual port bags? I eventually want to do front/back/side/side. My plan was 2) 5 gal tanks on each side behind the wheelwells, tie one in to the bags, use the other as a storage tank to fill the system tank if needed till I can get the compressor. Give me your suggestions, this will be my first air bag deal.
Thanks!
