I stopped swapping bars as much when I started using more sewn leather bar wrap. I wore through one on an intense trip, and took the opportunity to change from Rando bars to deeper drops. Sewed them up and now wish I had the old bars back.

You can tell where I like my hands...
I have tried stuff and changed it as my tastes, goals and desires changed, or if I found a part I liked and wanted it.
The biggest issue is storing the accumulating stuff that you have taken off, but want to keep in case its "right" for another build.
