Pro Valks are great. I highly recommend them. My bag use to consist of a couple of pros for distance shots and a max weight champ for a slightly more stable option. I also carried a P PD for windy days.
For whatever reason, I have a couple of Star Valks, one max wt., one about 166g, and both are very overstable relative to other Valks and just in general. Even doing the hot water treatments, throwing them into trees, and even into brick walls of buildings failed to make either of these Star Valks less stable for me. (By way of contrast, my Pro Valk did beat into submission, and the JL Champ Valks were not as overstable as the Stars to begin with.)
Ergo, earlier my suggestion of a max wt. Star Valk.
Also, as I read the first post, the OP wanted "slightly" overstable. We can debate 'til the cows come home about what that actually means, but I'd suggest that while the Teebird is excellent, the TL might be "slightly" overstable while the Teebird itself (especially in premium plastic) is more overstable. Ditto that for the Inertia v. Tesla. Bottom line, the OP gets to have the fun of finding out for himself what best fits his needs....
