i've noticed that on murnak cases the tubes are flush with the top of the case... is it hard to get the shafts out of the case like this? especially with joint protectors... the lid doesn't look like it allows for much in terms of making the top of the shaft sit higher than the tube itself. anybody have problems with this? i don't own a murnak so i don't even know if this is an issue but from the pictures it looks like it could be...
