I have had excellent results using those red plastic throwers that sell for under $10 at any Wal-Mart, K-Mart, etc. Don't know the brand name, but they're easy to find.
You get a lot of control that way--throw soft, throw hard, high, low, etc. And will throw much farther than the best arm.
The only downside is you can't shoot alone. You need someone with you to throw while you shoot, then trade off. But then, most TFL members consider shooting a buddy sport, anyway, right?
