I don't know about this, Loquita. You are a bit fickle when it comes to bags.
If I recall, there's a purple bag that you insisted you would keep. It appears that one got the axe.
Luckily, I don't have to think about cutting back right now because I'm very happy with the bags I have. However, if I had a bunch of bags that I no longer wanted, I would get rid of them and start over. I wouldn't necessarily go for a more expensive brand because I prefer the mid-range brands. Plus, I wouldn't cut back too much because I like to have some variety in terms of color and style. I have 9 everyday bags right now and that is a good number for me. I could probably cut back to 6 if I had to, but there is no reason for me to do so right now.
I hope you keep your Black Crash LM Midi and Black Haze 3-Zip MAC. I use my Black Crash TME Midi more than any other bag and I'm starting to get a lot of use out of my Black Haze 3-Zip MAC.
Good luck!
