Yeah I'm not quite sure where some of you guys are getting this info, but I'll take Andy's side too.
I think you picked a GOOD set of axles for your application. If you stick to 35" tires your 44 and 9" should be just fine. The nice thing about the 9" is that it's got the removable 3rd member, which makes setting up the gears much easier!
In my opinion though, you might want to just leaf-spring the rear for the time being so you can get it running and driving, and then worry about the nuances of a 4-link once you've got some more experience building. Even some small miscalculations with a link suspension can turn your truck from an off-road beast to a dog dragging it's butt across the carpet: all squat and no go.
Good luck! Can't wait to see more progress!
