You guys should do a video with the 600's dropping bombs.. see how far you can hit one, big nate on our team hit one 450 with them we google maped it and its on that video clip that was on here a wile back..
I hit with the 600's today and was dropping bombs with them, but nothing remotely close to 450', even with the roll.
They are fun to hit with and definitely fly. I wish I had picked up a dozen for myself when there were at $35, that was an absolute steal! If you can get them for $45 shipped now, which i think is the case, I can tell you that's a great deal too.
Another thing to note is that while the 600's are hard, I didn't feel like they were doing any more damage to my bats than Classic M's, and it was cold out (45-50). I once hit with some old ASA .47/.525s (white ones) and they seemed way harder and more damaging to bats than the Apex 600's.
