I'm in the process of purchasing a Halcyon Infinity BP /W, I plan on getting the SS back plate, but unsure on what size wing? I dive southern California cold water, wear a 7 mm and am 6ft, 280lb, I dive single steel 100s. Should I get the 30lb or 40lb eclipse wing? Your imput would be very helpful in my choice of wings. Thanks again, Vlad
