Does LA stand for Los Angeles ? if it does, drive up to Santa Barbara and you can kneel all you want on my floor to see what the diamond pattern feels like.
I actually don't notice it anymore but I have had my Racedeck a long time now (many many years).
Don't have my entire garage covered yet, its a new garage and I am only now finishing construction now but I have the front section nearly finished now. I forget who it was a few months ago that wanted to drive up and see the floor before buying, but I finally have some tiles down if you read this also.
Another thought is contact Jorgen at Racedeck and have him send you a sample tile that will be big enough for your knees to tell how it feels.
