Hi Jim! Thanks for giving the Mini flash at my wife - she was so excited. I told her I might have to take the car back if she doesn't respond in kind
I can't speak for the mini but I've used many mounts in the past. Even the heavy duty suction cup mounts (with the clamp) fail when attached to the windshield. THey will last for a couple of months, then they drop and you have to use hot water to reapply. The heat is just too much here.
The vent clips have broken off in the past as phones get bigger and heavier. In my audi I had one that would fit into the CD slot that I loved, but there is no such option on the Mini. I've also heard great things about pro clips, but understand your hesitation. On amazon I found this - maybe it will work out for you? It is on the dash so it's not fighting gravity.

There are also some mounts that incorporate wireless charging. I've never looked into them as my phone also is my wallet w 3 credit cards, and I don't want magnetic fields near them. Good luck!
