Brad, you may want to watch the video in full.
Cripps is good enough to shoot 300 backwards, just an issue of getting it on tape. But remember, while it's a lot of pressure in the 12th frame to throw a strike for a 300 forwards, throwing it backwards, you can see everyone watching you in your perepheral vision, so it's that much more pressure!
The response to my video has been incredible to say the least. I currently average 170 backwards in league, though I'm steadily improving. I shot a 192 average for 20 games in practice recently.
I'm after that free burrito Dan! (Assuming it comes with free airfare to Vegas)
