I was just out throwing star toros, luster ax3 and sparkle flx zone. I have thrown caiman in the past. toro is the beefiest, followed closely by the zone, then the ax3. The ax3 flight is different, and like a slower caiman. They fly straight, then gentle reliable fade, resist turning over. The toro wants to fade but thrown hard enough, especially fh, it will fly straight then fade pretty hard for a slow disc. It doesnt fade hard like a champ fb thrown slowly however. The toro is a great FH driving putter, shape flex lines well, very reliable fade. The zone is a slightly mellow version of this. I will snag champ and/or luster toro when it drops and i bet it dials up the OS a half notch.
after today, bh approach discs are a3, or ax3 depending, then if absolutely called for. FH approach disc and driving putter will be the toro. my main bh driving putter is the a3.
