My Pink/Black Alley Cat is laid out 50x5x30 (tall pin) as I wanted this ball to be an option for getting in on really dry lanes. I unfortunately haven't had too many opportunities to use it as the houses where I typically bowl are just too slick.
Lately I have been subbing at a house built in the 60's that has overlaid their beat up wood with Laneshield (a temporary cover) dressed with a 30 year old Phoenix lane machine. When bowling here everything that I typically classify as medium to weaker is too much. In order to find oil, I need to start with my Black Quantum or Pearl Freakshow at 4th arrow to get the ball through the fronts and the track hooks so much that plastic up 10 is a legitimate option to hit the 1-3.
Enter the Alley Cat. It provides me with the length necessary to get the ball down the lane without having to start left of the third arrow, yet finishes hard enough on the backend that I don't have to try to spin the ball. As the night goes on and the pattern gets even more beat up, I can chase what little oil there is left and still not fear about being weak around the corner.
Compared to other balls in my bag it is similar in shape to my Freakshow Pearl, but due to the extra length has me align my feet another 5-7 boards further right. In this particularly dry house it does well to compliment my BTU Pearl, which is another weaker pearl ball but slower off of the friction. I prefer the BTU Pearl when I want to get closer to the track on drier lanes, while the Alley Cat gives me more down lane motion to open up my angles and swing the ball to the dry. The Alley Cat has replaced the Outcast in my bag. In terms of overall hook they are pretty close, but I found the Alley Cat to round the corner a bit better while the Outcast is a little more hook/set. Of any ball that I have ever thrown, this ball most reminds me of the Electric Green/Black Avalanche.
I recommend the Alley Cat for anybody bowling on beat up lane surfaces. This ball will get down the lane with ease and make a strong move on the backend allowing you to chase what little oil there is towards the middle of the lane. If you want to fight the track then I would recommend the BTU Pearl, but for inside angles on dry lanes the Alley Cat is my ball of choice.
