Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!
I think you should be able to use your tripod case to put all the truss tube of your 11" dob.
Yes Weixing, I did manage to fit in the truss tubes in one of my padded tripod case nicely. Still got 2 other spare tripod cases (you have seen) to sell....
