Then you have to pull out the whole sleeve before removing the shaft? I'm wondering if simply pulling out the shaft while leaving the sleeve in the case will tend to collapse the sleeve and ultimately require you to pull out the sleeve all the time. I thought maybe a neoprene sleeve at least holds it's shape?
Sorry I misunderstood your question.
The sleeves are self-supporting and do not need to be pulled out. With the sleeves in the case works just like a regular case. Once set up you do not need to ever take the sleeves out if you don't want to.
