How many make an effort to install smart? I didnt and I'm paying for it. I carried rolls of 300lb plus carpet and vinyl by myself for years. I thought. I'm a big guy and it's too slow to use a dolly. In the last week, I've had 3 shots in my hip. I no longer do regular vinyl because I can't carry in the vinyl roller. Anyone else done this to themself? Maybe if you tell about it, we can get some of the younger installers to install smart. Any ideas to make it easier on the body? Ever talk to an old installer who didn't limp?
