Currently have the puttout as well. I too think it's a little slow. I also hate the fact that it's only 6 feet, and practice straight putts. I've noticed the carpet tends to lay one way (yes my floor is level), and I get about a cup of break...have to vacuum often to get it to lay straight again.
I've done exactly as Eddie has said. Built a putting green out of 2x4 and 2x6's and some Camry carpet. that thing COOKED. was really nice and could putt from some different angles. throw on some level spacers on bottom and create your own break.
I have a buddy who has the 13' well putt and he loves it...I'm debating that as we move into our next house shortly.
