I fully support the long hose (5' or 7') but I also show people that do not wish to learn that method that they can get the benefits of having a bungeed backup reg around the neck vs. on a yellow hose hanging around the waist where it might get tangled or fall down and drag. This can easily be accomplished by putting the octy that you have on a shorter hose and using a bungee and placing the primary on a octy length hose. You still have the distance you get with the "traditional" OW setup with the added benefit of always having a backup you know that you can get to if needed.
