amidst my LE lusting i had an epiphany about speedies. i realized that i now have 2 30's (MC and mirage) and am getting used to and liking the size. would it be a waste of time for me to replace my other two speedies (mono and damier 25s)? there's a part of me that finds the 25 a "cute" size. but it might be too small for me now. suggestions? advice?
