Delt, the answer to your dilemma is .... buy 4 more pins. Everybody has a spare pin or two they could sell. But you feel cut to the bone and that none of yours should go. That tells me you should really have 8-9 pins as your normal collection size. Keep your 5 pins and buy your next 3 favorites plus 1 really stupid em pin, putting you at 9. Then ask yourself, which pin should I sell? Pick 1 of those and sell it and you are down to stable 8's.
