Mikesolt, thanks for the input and encouragement, I am determined to keep practicing. I started with a 175 Leopard then dropped down to the 169, maybe I will check out a 150 class.
Blake, thanks also for the input. I have a few questions about what you said, if you don't mind:
"there are better discs to learn with than a leopard"
I assume you are referring to the Cheetah, Gazelle, Cyclone etc that you list later in your reply. Not disputing at all, just trying to learn, but why are those discs better than the Leopard for learning?
"at 250' your leopard probably shoudln't turn at all."
Just to clarify, it doesn't really. That was once, practicing in a soccer field, into a strong headwind. On a good tee shot it goes straight, then predictably left.
"if you are unable to throw the teebird at all, it sounds like a nose angle problem."
I agree that nose angle is likely a large part of the problem. I have experimented with moving my thumb closer to the rim, and I think this has helped get a more consistent line drive from the Leopard, but the Teebird still gets away from me, up and then left. Any suggestions?
Also, what do you think of going to a 150 class disc, as Mikesolt suggests? I don't mind buying different discs to experiment with, as long as it's based on sound advice.
