Each year I change or morph things I pick up during the past year that help my game. Some of it is true technique others come with experience. Feldbergs after the round impromtu clininc was an eye opener but so again is every round I play with my disc golf brethern. So in this line (and while protecting individual competitive advantages) whats on tap this year?
I'll start.
I learned to play with almost all forehand drives and seconds. Its been hard to develope a true backhand anny but the advantages are to great not to have one. I half heartedly messed around with it this last year but it is one spot I hope to develope. Well that and putting but that goes without saying.
when did you start throwing good backhands? 
field work is bombtastic, I can't wait to see the strokes drop off the card
Around the time you started throwing good forehands. 
I've been taking the dogs and kids down to Tower Street open space and working on CTP shots with my Roc. Just picking a tree and hucking. Working on turnover drives, spike hyzer approaches, long straight shots, short forehands, etc. I don't know how much it will help (the best practice for shot-making is to go to a course and make some shots, I think) but I am having fun, and getting reaquantied wih the Roc. On a side note, that Kelly Island open space land would make a wicked course.
Sounds like it will help a lot. It seems like there are two types of practice: 1) bettering your skill set by familiarizing yourself with your discs and working on consistent technique, and 2) translating your skill set into the best possible score in a scored round. The two are pretty darn different (although closely interlinked--more confidence in your skill set should translate to better ability to produce the result "on demand" like in a tournament), but each is absolutely essential. Sounds like you are working more on #1, and every minute will be useful! Try and take each practice shot like you would a shot in a tournament so that you are practicing the right type of throw..."rapid fire" practice isn't as useful, because you never shoot rapid fire in a tournament and the confidence gained won't translate.
did think we needed a whole "new" topic for this, but..... check out the wicked twist on his left hand! wow, almost looks like it hurts!

He's getting ready to "Hadoken!"
Down, down-right, right, punch.
Now to be a Am....you need to throw a 1033 rated round???
The best thing to help development is working on your backhand in the field. No worries on losing discs so you are able to develop the technique faster than on the course. It took me about 3 months of practice to learn to throw a good backhand.
Get ahead of the game...throw Gateway!!!
