[hijack]I've done wreck dives where there is a stiff surface current and the boat is tied into the wreck (Spiegal Grove, Oriskany, Hydro Atlantic). If you surface away from the ascent line, you run the risk of being separated from the boat before they're able to break mooring and come and get you. If there is a stiff surface current then you may not be able to swim back on your own. Sometimes surface conditions are rough and staying under and surfacing close to the boat is preferable too. I also know some people that dive in rivers and their dives take them into shipping lanes. Surfacing there, away from their boat or shore could be disastrous.
My dive planning includes enough gas to get me and a buddy back to the ascent line/point of origin and surfacing in the event of an OOA emergency in situations like that.
I can think of several pluses to using a longer hose, even for an OW diver and no real negatives to it. But as we've both said, if your method works for you then to each their own.
