So after playing it (almost exclusively) the past few weeks, the main difference in playability I find with all my other guitars including my other T-styles, is the neck radius. As mentioned, while it is not the "baseball bat" associated with some '50's models, it is still noticeably thicker than what I'm used to, especially as I go up the neck. What I'm finding is that as I "dig in" or bend a note up there, there is more a feeling of control as you really have something to grip on to.
Not something I would want to shred on (if you're into that), but for playing the blues I'm really starting to like it.
