keep the Pap and get the Speedy for now-- after you've had the Speedy for a little while, you'll know whether you want to keep the Pap or sell it.
Keep it! I love my Damier Pap 30 and still use it alot, even though I have a Damier Alma, a Trevi and a Damier Speedy. Pap has its own special style. Interestingly, it's one bag I always get compliments from men on. I think they like the shape.
I would get speedy and keep both for a while, and see if papillon stays in the dustbag all the time
