Uh, uh maybe it is. I am just going off of what I have heard. I actaully have never tested the therory. And knowing me, I am prbably way of and wrong about the rectangle vs square thing any way. For me a 9x9 would be just too big and "weigh" too much for my tatse. I guess that is the bottom line of why I chose a rectangle.
