I had a Klockwerks Flare
(not to be confused with the shorty Victory Flip
) for my first riding season. I never used the stock XCT tall windshield (sold it, without its ever being mounted) because I never want to look through windshields (and did a lot of Vic test rides before my purchase), but that's me.
I liked the Flare a lot, but replaced it earlier this year with an 11" Madstad system ( http://www.madstad.com/s.nl/sc.7/category.2446/.f
), just to try something new. For my height -- 5'9" -- and normalish torso, they are both very good and very similar in airflow. Height is very important, more so with the Flare; I have a riding buddy, 6'+, and for him the Flare was too low, resulting in a little too much buffeting. So keep that in mind. The Madstad comes in 9", 11", and 13", and is adjustable, anyway (and pretty inexpensive).
Don't worry about the XCT mounts. All you have to do is remove those extra brackets on the XCT -- the ones that support the barn-door windshield -- and, voila, you have an XC, in terms of windshield holes. I just said I had an XC for my Madstad order, and that was that.
Back to the Flare. It didn't bother me that the Flare mounts underneath the fairing edge.
I have a few pics of the Madstad in my gallery (link below, in signature). For the Flare, I have 32 pics that I put up in a separate group months ago, when Klockwerks asked on some forum if anyone had any pics they could use. That group is here -- http://www.billanddot.com/klockwerks-flare/
-- and includes a few detailed mounting-area shots.
Hope you find some of this info useful.
