I moved to a wing after 25 dives. Far from being harder to use it was easier - no pockets and useless clips and bits, and more importantly it was much more comfortable and it made me feel less squashed on the surface. I have no idea why the myth that you have to be experienced to dive one persists - probably due to the history of diving.
I know many divers who have learned to dive in a single wing and know nothing else. I put my ex-husband in a wing after his open water course and he found it much easier to cope with than the BCD that his dive school insisted that he learn in. The long hose took a little more getting used to but that's not open for debate here.
A wing weighs four fifths of bugger all and twinned with an aluminium backplate your luggage allowance won't take a serous hit. Just as importantly, they dry out very quickly too - no pockets to keep the damp in - just inflate and dry for an hour or so in the sun.
You have had offers to try out kit so take them up - particularly if you have pool access. Then you can choose what you want
