Thanks Pikelet. It does almost look like the 505 red that I loved so much but never got the chance to own.
I went back and played with the 350 today. It hurt my eyes on Medium

I think that puts the nail in the coffin for the mini.
I also accidentally scratched the shiny finish of the silver 350 with the black 650. So, maybe their build quality has deteriorated over the years... or maybe it was just a scuff. I hope it was just a scuff.
