I am writing this post to provide some feedback on a purchase or two I made after reading recommendations from other posts.
A few weeks ago I ordered an armrest from Doug Edwards (the "McClung" model). A week later, I had the armrest. I sent a photo of my mandolin by email with my order, and Doug did a great job matching the finish to my mandolin (a Flatiron F5 Festival, made in Nashville after Gibson's acquisition).
My observation is that this is a huge aid for positioning of the forearm and and wrist, at least for those players who seek a bit of arch in the rest (i.e., who do not play with the bone on the heel of the palm resting on the strings, leaving a flat wrist or even a reverse angle with the fist pointing above rather than below the wrist).
It requires far less tension or concentration for me to get an angle in my wrist. I reattached my pickguard after the armrest came and, combined with the armrest (which my fingers will touch lightly for reference when I play with a freestanding wrist), it has made it much easier for me to tremolo with an arched wrist.
From my perspective, the armrest does not effect or impair the resonance of the mandolin, and if anything improves it. That is because the part of the armrest that attaches to the mandolin (much like the way a chin rest attaches to a violin) does not extend beyond the edge of the top and bottom of the mandolin where they attach to the side of the mandolin. Without the chin rest, my arm covers more of the service of the mandolin's top and had more of a muting effect on the instrument (not a huge difference, but noticeable nonetheless).
The real advantage, however, is the way it makes it easier to play with minimal tension with an arched wrist. As one other observation on equipment, I just received the Wegen TF140 pick last week (triangle, bevelled, with holes in the pick to aid in gripping it). Combined with the more arched wrist, I am getting a level of tone out of the instrument that I have not gotten in the past.
No financial interest in the armrest, Wegen picks, etc. But I wanted to thank all of you for your various pick and hardware recommendations that helped me make some decisions. And thanks to Doug for making a great armrest for a very reasonable price!
