Well, both the 7' and 5' hoses route across your chest -- the 7 footer just routes up and across, and the 5' hose routes more straight across. Either hose must be run either over or under the light cord. With either, you have the length of hose from your mouth to the point where the hose crosses the cord (assuming light cord over) to donate, which is plenty to establish the air-share. Once the recipient has gas, you can calmly sort out the light cord and deploy the rest of the hose, whether it's a 5 footer or a 7 footer.
I don't think there is any particular difference between the two in the deploying process. The big difference is in the swimming, where the 7' hose gives you more options for positioning the two divers, and allows you to get far enough apart to frog kick, if you are swimming side by side.

How about getting a 6 ft hose and pleasing both camps 
lol
A lot will depend on if you use a 90 degree, 120 degree or straight connection to your reg - although the main reason for using a certain length is what you are comfortable with.

Well as far as clean routing is concerned, a 6 foot hose is a perfect fit for smaller framed divers using a can light or shears/knife pocket to hold the long hose in place without excessive routing concerns. The problem lies in that the hose may not allow single-file air sharing exits through a restriction like you would find in a cave or wreck. A 7 foot hose will allow all but the tallest divers to do so comfortably.
Also, most divers don't find it necessary to use an elbow or swivel on longer hoses, especially those of us using miflex hoses. I have one on my singles reg with a 5 foot primary hose, it's not DIR but does make up for some of the lost length of a 5 vs a 7 foot when sharing air. That being said, I could lose it tomorrow and shed no tears, its not that important to me any more.
Peace,

...and now we've come full circle - why use a 7' hose on singles, as per the OP
