Just threw this for the first time today.  Very impressed with the results.  The ball gave me good length and a strong continuous finish.  I only left 3 10 pins for 6 games.  The ball was very continuous threw the pins and really threw some messengers around. Couldn't really compare it very well to my other equipment due to a change in my grip.  I shortened my span by about 1/8" and changed my thumb from 1/4" reverse to 0.  Thanks to Dave Roberts at Imperial bowl for working with me on the grip change.  I think this grip allows me to stay under the ball much better and hopefully will cause me to not spin the ball so much.  Also, so far, my hand feels much better after wards than it did with my old grip.
