Haven't messed with the TL much, but...
I have no trouble getting my teebird to fly straight, and when I want to go longer, I use a wraith. In my experience, the wraith will fly very similar lines to the teebird, but 30+ ft longer. Because of this, I didn't see where the TL would fit in my bag.
I like the teebird (and wraith) because:
1. Keeping it low and giving a little hyzer-flip produces straight lines.
2. A flat throw with a little more height will fade predictably at the end.
3. It will hold a nice hyzer line without crashing out early.
4. Pretty much zero turn from the teebird, and only a slight amount from the wraith, unless I release poorly.
5. Will stand up to a medium headwind quite well.
6. It will hold an anhyzer quite well, as long as you get it spinning. It doesn't turn and burn like my roadrunner is prone to, especially on a hard anny line.
