I am moving to a BP/Wing set up. I was at my LDS yesterday and was talking to one of the DM's about what type of wing to buy. He recommended the DR Rec wing. I dive an AL 80 and 3mm full wet suit most of the time and travel occasionally. Eventually I would like to learn to dive doubles. I have looked at single tank wings, but he said they were not very versatile. He said thew Rec wing was good because it has the bungee and could be used for doubles and singles. He did not try to have me buy it at the store. I think this was his true opinion. Any input would be appreciated. Thanks.
