Much delayed follow up!
Per MattKing I went with the Ektar in 6x45 Super Ikonta. When the scans came back from the lab, I stupidly forgot that Mike's Camera produces dogcrap scans, and hid the film away in a drawer as a reminder that I am the world's worst photographer. I later learned that this is a very popular location for engagement, pregnancy and baby photographers. It appears that a lot of them bring brooms or rakes to clean up the trash before they shoot (lesson 1). They also shoot the west (best) side of the ravine in the afternoon so there is no sun dappling. My morning shots had really blown out highlights in the dappling (lesson 2). In the intervening 8 months there have been some interesting apug posts about scanning technique, so I decided to try out the recommendations on this film. That is, do a straight scan with all adjustments turned off and do all the work in a quality editor (lesson 3), in my case, Photoshop Elements 15, the last one you could buy instead paying a monthly fee.
I think the results are not half bad, definitely good enough to make me want to make some adjustments and go try again.
