FWIW, I prefer a wing most of the time over my greenland paddles, including for surfing (for a killer low brace when side surfing). I love their efficiency. For me at least, a wing paddle is also great for stability and bracing as long as I can keep forward momentum going. When I'm in big (for me) very confused seas however, and not moving (eg spotting my mate while he's rock gardening, or just holding place while I evaluate a situation), or when I'm tired, I much prefer my GP for predictable bracing. I also find it a bit easier to set up a roll wirh a GP, although it's not as powerful as my wing in a roll.
Speaking of wings, I prefer the Jantex Alpha small over my Jantex Gamma small. Although it's not as powerful, it's easier on my shoulders as it has a softer entry and a longer efffective atroke. The Gamma has been described by some as being like putting your paddle in cement, the catch is so firm, and you can really feel the difference in initial drive thru your feet on the footrests. My mate's call it my outboard motor but it does wear me out
