I drilled 2 so far and both have been quite a hand full on a typical houseshot with super old surface. I like to overall reaction of my 40 x 4 1/2 x 20 on a house condition that is ultra heavy and use some super slick oil SD-40 I believe it is called. I like the 50 x 4 x 55 with a p2 hole on house conditions that are a little more open and more surface on the lane panels. I also used this one more on the KEGEL patterns more then the 40 x 4 1/2 x 20. I practice and great bit on 8/1/11 on really burned up house condition I think the 50 x 4 x 55 got better reaction as

my practice seesion went on.

 

I hope I have provided some insight for you. I like this ball better because the Theorys start up a little too soon

for me and the Infinite tends to be a little later then I like on house conditions. I love the Infinite playing a straighter

line on the fresh... Overall the Critical is the best all-around ball I found recently.

 

 

I just got one drilled Saturday 4 x3 and this ball is wickedly strong. It is much stronger than my 4x4 Theory and better carry for me I definately recommend this to anyone who likes to swing the ball to the ditch and watch it come roaring back...
