Drilled my Knockout strong (45x4.25x25) as I really wanted a big symmetric ball in my bag for when tournaments return. I have always preferred symmetric balls for the way they smoothly transition down the lane and having liked a number of balls with the Melee core, I was really looking forward to this ball!
The Knockout did not disappoint! It gave me more hook than expected and really corned well down lane - especially for a solid. The best way to describe what this ball does is the strengh of the Melee Hook with the Purple Edge ball motion!
I have so far used it on our house pattern, 41' Beaten Path and one of the Weber Cup patterns and have liked what I have seen. I have had some success keeping my speed up in the track, but my look got better as I moved in to the 3rd and 4th arrows. The big sweeping arc was easy to control by tinkering with my hand and as the pattern dried out I was able to amp up my speed but still see the ball finish on the back end.
Compared to other balls in my bag the Knockout is a few feet earlier than the Melee Jab Blood Red with the same strong move on the back end. The Knockout started up just a pinch later than my Hero Solid but had a stronger, more continuous move on the backend. In terms of ball motion in my current bag it closest compares to my Omni Solid (but a tad weaker).
I recommend the Knockout for bowlers of all styles on medium oiled conditions. This is a very versatile piece that could serve as the benchmark type ball for rollier players or as an upper end piece for those who are softer with their speed/rev dominant.
