I was watching Brunswick''s C-System 2.5 video on their website today and something caught my eye.  At the end they have throwbot roll the ball with 3 different axis rotations, 60, 40 and 20 degrees.  Same revs and same speed.  What was interesting was the actual appearance to ME of the axis rotations.  60 degrees looked like 40 degrees, 40 like 20, and 20 pretty close to end over end.  In the past I''ve estimated my rotation to be around 60 degrees, but now that I''ve watched this video I''d put it more at 75-80 degrees.

I''m not saying that everyone underestimates their rotation, but I''ve seem some people claim as low as 20-30 degrees.  With the way the ball looked going down the lane at 20 degrees in the video I can say that I''ve seen maybe 1 or 2 people in my life with that kind of rotation on a regular shot.  Sure some guys can kill rotation to go up the boards, but there is no way you''re playing inside of 10 with that kind of rotation.

Here is the video I''m talking about - http://www.brunswickbowling.com/newsLetterStorage/C-System_2-Low_res.wmv the throwbot stuff is at the 5:20 mark if you don''t want to watch the whole thing.
Thoughts?

I thought it was just me till i realized how much my ball was skidding thinking I was at 45 degrees. but then i pictured a bowling ball at 0 and in my mind turned it 45 degrees... now it made more sense that 45 degrees wouldnt seem like much when standing straight behind the ball.

so id agree with you. id imagine that most people think their rotation is much less then what it really is.

300 revs
16 mph
17 degrees of tilt

when you're feeling blue,
just say to yourself "what would BallBaggins do?"

place some tape on your pap and watch the roll.I have about 45* on my normal release and always thought that was much less then most.I often need a high rg polished pearl to play on the same lanes as others with the sanded hook monsters because of their high axis rotation.
