I'm currently running he Bestop Bikini with the wraparound windjammer / duster.
I love the set-up. Its not 100% water tight, but I can' say that the full soft-top's been off for about a month now...
The bikini goes on in maybe 5 minutes and comes off in about 2. Well, after the first time / learning experience that is..
