I apologize if I'm repeating a common question but I searched and didn't find an answer. Correct me if I'm wrong but I believe the valley's use k55 profile and dynamo's k66. K66's are about an 1/8th of an inch narrower so the playing surface measures out at 44 1/4 x 88 1/2. Still a rectangle but wider. Is that standard from dynamo? I know that no one that plays here really cares or even knows but I'm curious. I could easily put 55's on them and have a 44x88.
