H2 Lift Kits

[KYBOB]

I am thinking of putting either at 6" FabTech lift kit or a 4" Rancho lift kit in my 2004 Hummer H2. I want to have better off-road clearance, but it is also important that I continue to be able to drive my H2 at interstate highway speeds on-road. I use the H2 to commute around several states for business, but also enjoy off-roading it. So. . . I'm looking for the best of both worlds. I'd like to hear from anyone who has put a lift kit in his/her H2. How did it affect on-road and off-road use? Would you do it again if you had the decision to make over? What suggestions do you have?

Thanks for your reply.
