Quoted from Monster_Bash:Both..
It seems my sell windows is couple months. If it doesn't get moved by then i'll have it 'forever'
Same. I like to rotate some pins, while others are keepers. Among my EMs, the only keeper is Fireball while Jet spin could leave if I find another interesting one from the same area (70's).
WPT is a keeper - would probably consider temporary trade against WoF or Avatar.
Spectrum has sentimental value. It was my first pin and is still there.
Sometimes I can't resist buying a rare pin when priced right, to discover after a few days this was not for me. These ones are gone within weeks. Not enough space to keep a pin I do not like.
