I LOVE being a lefty, have my whole life. I have a twin brother who's a righty(aka "normy") so we do the mirror image thing on the course.
As far as disc golf, I find my advantages when I can. I do make note to see which courses favor which arm, and whilee many are well-balanced, there does seem to be a righty bias in many a course design.
I am ok with this, as a mostly LHBH with a developing FH. I actually love throwing annies, so righty holes aren't so demanding UNLESS they finish hard left, to which a flick would be ideal but is not nearly as dialed in.
As far as pro players go, I know Devon Owens is a lefty. I've seen quite a few pro righties throw bombs with their left hands too.
in the end, I just wish I could switch hit off the tee like I used to in the batter's box.
