We flew into Kona last week with my wife's SC. First trip with it. I don't think cases are going to be the limiter in packing these things. For her's it came down to the front brake cable. The bike has the 50/10 stem with the non-UCI legal stock bar so this configuration likely yields the shortest length of cable out of the bar. It leaves no room for removing the base bar from the stem and securing it flat against the frame. If you had the stem adapter configuration the cable issues would be no different than a standard front end. For the SC I had to pull off the front brake cover, and pull the cantilever wegde out from between the brakes to get some limited cable slack. I was able to get it in a Thule case this way with some foam and bubble wrap between the frame and bars. There were no options for rotating the bar assembly to the best location. And I don't like the resulting height/thickness in the case. A solid hit in the middle of the case could cause some damage to the bars and/or frame.
The plan when we're home is to look at some options for getting the wedge off the front brake cable. Perhaps tinning the cable so it won't unravel, but can't do that on the bike and it may be difficult to feed the cable through the bars after adding solder. Some case bracing like those used in the S&S cases may be an option too.
As it is right now - to disassemble/reassemble this bike requires removing 3 small screws from the stem cap, the 4 base bar to stem bolts and the two small brake cover screws then finding a safe place for the fragile stem and brake cover pieces.
She loves the bike. Though that may change on the first trip she makes on her own!
P.S. Her SC has the same draft box problems with tire rub that others are complaining about. I am tool and parts limited this trip and have only tried electrical tape shimming options. The rubber inner tube fix mentioned in this thread is the next try when we get home. It is now off the bike as all shim options eventually resulted in case slippage and then tire rub.
