Are you saying that you would like to re-join the AOA, but are not keen to pay the full amount of your back dues?
What percentage do you think would be reasonable?
Perhaps they may entertain an offer from you or otherwise provide some sort of a discount.
As they say in the Classics, "Membership has its privileges" (and its price). Only you can put a value on that when considering your personal circumstances. Good luck with making the right decision.
