Hey Dave, its discrimination.
All courses should be 50/50, I dont care what the left handed population percentage is, its still not fair to punish one group of throwers.
My favorite courses are the most balanced ones, which require me to use a vast array of shots, both from the tee, and the fairway, not just huck and pray backhands.
The reason I made the statement about designers is, I'm tired of poor planning resulting in a waste of 9, or 18 good targets, placed poorly in the wrong locations.
Disc golf courses should make you want to come back, again , and again, not be a one shot wonder.
I think more thought, and input, should be required, rather than just one person pulling the strings.

Now, back to our regularily scheduled program.
As far as you carrying only overstable discs, this is not going to allow you to improve your backhand throws very well, and will probably only encourage bad form.
I carry across the board molds. My longest most reliable backhand discs are the slower , less stable ones, my Valks, Wraiths and Beasts.
My best forehand discs are the Innova big 3, the Boss, Xcal, and Destroyer.
You need to work hard on one throw first, it will take you too long if you try and learn both BH and FH at the same time.
Keep your less stable discs and really work on gaining the best understanding of how they each fly backhand.
When you have an opportunity,maybe a fairway upshot, try flicking a more stable forehand disc.
Once you have what you consider to be a competitive backhand, which is being able to throw hyzers, flat shots, and anhyzers with accuracy, then start working on forehand drives to level the playing field with all those lazy righties.
