Brunswick Endeavor and Ultimate Defender - The Core of It - Bowling Buckosh 

excellent information..very interesting..thank you

Great review!

Just wanted to post, got the Endeavor because the lanes here tend to go away pretty quick. I'm fairly matched speed/revs between a stroker and tweener (I like going up the boards, but can move a little left). At our State Open, I tried to start with the ZigZag and Break Away, but (on High Street pattern), the balls saw friction way too soon for me. I dropped down to the Rhino Pro and when it went away, went to the Endeavor and averaged right at 230 for 18 games (over 2 weekends). The Endeavor worked as you said, it was super clean through the heads and picked up nice at the end of the pattern and pushed through the pins. I had to keep my speed up pushing the ball right because it was really responsive off the friction (without being uncontrollable). Awesome videos. Thanks

The Endeavor core is super interesting. Question for you - I am looking for a pin down option and want to go with an asym core for something smoother. Something that would fit under the Black Widow 3.0. Do you think the Ultimate Defender is a good fit? Thanks in advance!
