Yep it's definitely a temporary thing. I've done this once after busting a u joint and it seems like 45mph was as fast as I wanted to go. It just didn't feel right. Perhaps someone else can shed some light.
I use my cj7 for hunting club mud from Oct to May and I really like the twin stick. I can slip the front in and out of high or low much easier than with the single. Also, with a locker up front, I can disengage for quick turns or when the ol gal seems to be going her own way through the mud. My only issue has been the boot. I wish someone would make a solid base, one piece boot that would flex well with the twin stick. As the rest have done, I had to cut/heat/bend/etc to get a good set up. I'm very happy now.
