Reminds me of the old joke, what do you call a boomerang that doesn't come back?
A stick.
A stick.
For fun, I learned a palm up curve:
The palm up is a fun pitch to play with, but the more drive and effort you put into it, the more spiral it becomes. I'm 6.4 and have very large hands and long fingers and it takes me several throws to get it really moving. I think this pitch is great for helping develop body awareness, but unless you're long and lanky, it's a tough pitch to get to work in full motion.
