Did not slot the holes; was able to utilize the existing holes by carefully starting and simultaneously tightening all three mounting bolts at the same time. I addressed that gap issue by using 5/16" foam insulation tape.

Am curious to see the new adapter plate and how they addressed the gap issue.
As far as your questioning o the shield size that you have; I am 5'10" and have the 13" medium gray shield as well. At full height adjustment, I an looking just through the top of it. That is fine for me. You can get used to it.
I'd like to get the 15" in a more lighter tint... for the colder months. Right now the 13" is working fine in the cooler fall temperatures we currently are enjoying up here.
