Success! It turns out that many a technique problem was at the root of my driving difficulties. No surprise there.
I didn't take the advice of throwing Cobra type discs as my driver, but instead picked up a 165g pro Leopard and a beat to hell Ace that a friend traded to me. I really wanted to work with something that had a driver-like rim to make sure I was putting proper emphasis on throwing nose down. The Ace was particularly helpful because I was able to actually flatten it from a hyzer and make it helix shortly after i began throwing it. Having a frame of reference for how to make a disc fly as desired, I was able to teach myself how to duplicate the same thing with other discs to an extent.
A week or two with the Ace, and I felt like I had outgrown it. Here is my current driver set up:
165g pro leopard
167g dx teebird
168g 11x teebird
The Leopard probably makes the sweetest throws for me and is great when I need a right finish or distance in between a mid and a teebird. It will turn out of a hyzer release for a long ways then come back before it hits the deck. Teebird pair gives me a good straight disc in dx, as well as the champ version that finishes predictably to the left. I reserve the Orion for when everything is clicking and I'm feeling saucy, where it gives me more distance than the other discs. Of course if I'm not throwing well on a given day I will tend to put it nose up or something equally dissatisfying. I have a handful of other drivers but none of them are as sexy for me as the ones listed above.
The technique repair section of the website has been a tremendous help, as well as the link to area46. The photos on that page allowed me to get a better idea of what my footwork and pull through should look like. Now its largely a matter of training my muscles to do it consistantly.
