I just replaced the supply hose on a toilet; the hose is a little longer than the distance from the toilet to the supply pipe, so there's a little bend in the hose. I bought the hose that was as close as I could get to the actual distance, but after putting it on I started to wonder: Is it better to use a hose that's just a little longer, and have a bend at both ends, or it is better to use a hose that's long enough to make a complete circle? That way, there's no bend stress at the connectors.

Yes, I really do have better things to do than worry, but I just read a review from a guy who replaced his washing machine hoses with the braided-steel, guaranteed-never-to-leak-kind, and one of them exploded after about 3 months! Now I'm paranoid, because I was about to get some of those myself!
