Hey @slaw I'm late to the party here. Had a few minutes between jobs, saw the link to the review, and gave it a read. Congrats man.
'My' MyMat is still in use on my SOTA, and I have no plans to replace or remove it. It works and it does what you wanted it to do, and I like the presentation it offers......without a clamp ;-). That was a tough one for me to get used to, but it does bring out the best in 'YourMat'.
