A recurring theme would be nice, like all the same wedge material or all the same center pin conchos...
These Filarmonicas were done that way

I drove myself crazy on these trying to get them perfectly matched

They are handmade products so no matter how close a pattern you try and follow, there will be tiny inconsistencies that creep in...That sets my OCD off but I guess some people can handle them not being perfect..
See horn would do that for me because they would never be matched unless they were just plain black horn, those differences in patterns in the horn would drive me loony tunes :)...
The solid Acrylics, I like so much, or perhaps the Carbon Fibers or the G-10 like Max does, those would be much more pleasing to my brain... but then again I admit to being weird hehehehe
No matter the scales I bet they will be an awesome set.. Enjoy !!!
