T-Scope owners

Bought a 14" f/4.7 T-Scope about three years ago. Wanted to find as much aperture as I could in as portable package as I could get, along with good optics. Certainly haven't been disappointed in aperture, weight or performance. In fact, I've been very pleasantly surprised by the Obsidian Optics mirror. I'm no star-testing expert by a long shot, but I'd guesstimate the final wavefront at ep to be 1/7 or better. Find myself wondering if there are other T-Scope owners out there who have been as satisfied with their scopes as I am. Also, whether other owners have found any useful upgrades to the packages they purchased, especially concerning counter weight systems, as mine sometimes gets overloaded with binoviewers. I DON'T want to start an unpleasant thread concerning delivery times, as we all know they are long with this company, and I had to wait a long time for mine. Just looking for other's thoughts on performance and upgrades.
