SHORT: Maybe a Roc of some sort, thrown with medium power (no more than 60%) flat, given that I have enough arm speed to throw a speed 10 SL around 300 feet consistently. Maybe aim a little bit to the right to account for the lack of speed.

The other alternative, for me, would be to crank (85%-95%) my JK Aviar with slight anny.

LONG: I would RHFH my Star Firebird (80%-85%), which should go anywhere up to 250, given a good hard crank.
