I have an Halcyon hose on my Oxycheq. And I may be wrong, but I thought the current inflator on the Halcyon is the same OEM as the Oxycheq (and OMS for that matter).
In any case, inflators and hoses should never be a deal breaker in the consideration of wings.
It does look like the same OEM on the outside. The Oxy is about a pound heavier dry than the H, probably because of the "extreme" covering. Is there really any difference though when it comes to performance in the water? I mean, they are very close to the same shape, same displacement. I am getting pretty nit-picky here I guess. Any clue as to which would sell easier?
