Well I went with the 3/4 4' x 6' sheets from http://www.jjdog.com
liked the sample they sent me...the rubber is very thick and virtually scratch proof. I had to compromise though...no way at this time I am plunking down almost $2000 to do the whole basement. I don't plan on being here forever, and I'm not sure if that would be a huge selling point if I decide to sell my house and potential buyers don't have dogs.
So I measured off an area that covers the main traffic area that I work the dogs on...it wound up being 8'x32'...plenty of room for me to set up weaves and a couple jumps, and to give Solomon room for quick turns and jumps on the flirt pole.
I'm 'only' going to need 11 sheets...they are 100 pounds each
I have NO idea how I'm going to drag them down the basement when they drop them off...I guess I'll have to bribe my neighbor to help by frying up a bunch of chicken for him
And if I move, by God, I want all 1100 pounds of matting to go with me. I'm not going to seal it to the floor, just lay it on top of my existing rubber mats...at 100 pounds each, I won't have to worry about them sliding or buckling at all.
