Air, Static or coilovers?

[1enick72]

Working on my 2nd truck so I learned a few things that I want to make better on this one. I've done a pile of research but not finding the answers I'm looking for. Hopefully Someone can help me out.
I want a 5" drop and want it to handle and ride good, just a good cruiser but I live in Maine so the roads suck. My old truck had 2.5" spindles and 2" springs, 3" springs in rear with 2" blocks. Front was very stiff and rear was very soft, not a great combo. I'm definately leaning more towards air but I've never driven anything on air. My guess is the ride is good but I wasn't sure about handling, lots of hilly curvy roads up here. I have been looking at coilover setups as well. These have me interested but I know very little about them or how they would feel driving around. Thanks for any help.
