lil mynx/ xpole grip size..

I currently have a lil Mynx black powder coated rotator/static pole. I keep my pole in a room with an 8 foot ceiling. I really am considering a removable pole for my living room which has 12 foot vaulted ceilings because I can't get the ehight when I try to invert I'm struggling not to kick the ceiling 😮 . I am not sure if I should go X-pole because the coating is different ( steel and chrome and brass) I'm not sure which is going to be close to the grip I have on my lil Mynx. Also, I was wondering which size 45mm or 50m is going to be the same circumference of the lil mynx. Just in case anyone knows this off the top of their head, I'd like to have an idea before I commit. DO they even make removable poles for this height? ( hubby would kill me if I even tried to put a perm on in front of his flat screen 🙄 ) anyway ladies, thanx for you time you are all awesome!
