I started with 2 74's in my backyard and planned on finishing with a built 74 but after taking the top off a few times by myself, I realized that I wasn't going to be doing that much. I'd think about the wheeling you do. Are you taking friends out? Will you be doing a lot of social type wheeling where you want to have folks with you enjoying the scenery and the ride? Would you consider a soft top? Or, are you going camping, exploring, etc. with it by yourself or just with a friend or family member.
For me it came down to the fact that I wheel by myself or with a buddy, don't ever take the top off, sleep in the back sometimes when it rains, carry a lot of gear, and don't hard core on the rock crawling like the Rubicon. I explore the desert and go for long trips at a time. So, the 2 74's got sold and I went with a 76. The top hasn't been off yet and probably never will. At the time we still had the 30 year rolling exemption for smog but good old Arnold screwed me big time after I got the 76. Missed it by a year.
