B + W 40, Yellow/Orange 16 (shadow details)

Hello -

I also posted this in B&W but not sure if it is the right forum.

Anyhow, I'm a long time B&W film shooter and wanted to buy a #15 filter (which I use with other cameras) but most manufacturers (Heliopan and B+W) are backordered for months. I was going to settle on an orange #16 instead. Two questions:

1. Is the difference between #15 (deep yellow) and #16 (yellow orange) quite dramatic?

2. Does the #16 filter "crush" the shadow details or are you still seeing enough to maintain reasonable details in the composition?

Note that these filters will be used on medium format Mamiya cameras.

Thanks!
