...I like the idea of the super 30 kit (superior just released it a month or two back I guess)... only potential (and I say POTENTIAL) disadvantages are the small ring and pinion in the D30 (as long as you don't go lower than 4.56 this should be ok - I've got some nice pics somewhere of an exploded set of front 4.88's from a TJ D30), low pinion, and thin tubes...
For you Coops it is a no brainer - you had all the stuff you needed already (hub kit etc)... if you were building a D30 from scratch though a D44 swap would probably come out at a similar cost all up.
They are also doing a super 44 kit that will run 35 spline axels in the rear D44...
Keep us informed on how it goes.
