If anyone is interested videoballreviews.com has a video up by buddies pro shop up under the Siege. Probably the best video I've ever seen featuring Johnny Petraglia Sr.(one of my Favorites.) Talks about different layouts and reactions. They also show Johnny from multiple angles throwing the Siege, Wild Thing and Python. Like I said probably the best video I've seen, roughly 7 1/2 minutes long.
It is the video on the bottom.

id agree that it is one of the best videos ive seen done.

ive always liked the way johnny throws the ball. still wont forget last year poking fun at finding a johnny petraglia ball and then feeling someone tap me on the shoulder... im thinking "huh??? whos that" hahaha it was johnny petraglia himself... whoops! LOL

I had no idea he was bowling at that center in that very league with my friends father.

Well I'll concur.  That was a great video.  I like the in depth info on why/what he uses each ball/layout for.  Pretty cool.

Actually there is a vid right below him of Mr. Sr. throwing the balls too
