I've tried 4 TDs, and other than one stiff 171 S-TD, they've been pretty much like you described. Not much turn, at least at first, will hold an anhyzer for ages, very good glide. My max weight C-TD and my friend's brand new high 160s S-TD are pretty identical, reliable, controllable turn. My gummy champystar max weight S-TD is beaten in and turns more, fades even less and is my favorite hyzerflipper. Terrific disc.
The stiff 171 S-TD is another disc altogether. Very high PLH compared to the others, very little turn, starts to fade very soon but the angle doesn't really steepen, meaning it'll glide a very long way to the left (RHBH). Very much like a high PLH Opto Vision. Don't really know what to do with this one, so I don't do anything with it.
