I'm so glad you brought up Synergy Instruments, Ontario, Canada
I have 2: a full CF Concert I got about a year ago and a Hybrid eKoa/CF that I
was able to get around June 2021.
The reason I got the Hybrid is because although I loved the full CF construction
of my initial purchase, I found the upper part of the neck, particularly around the
headstock, a bit thick. And although I was getting used to it when I was playing it
almost exclusively from Dec 2020 to June 2021, I was contacted by a Synergy
(Authorized?) Dealer, also in Ontario who mentioned that his comparison of the
full CF and the Hybrid revealed a volume advantage to the Hybrid.
This was very interesting to me because beside the full CF neck thickness, I also found the volume
a bit muted. I often lead Song Circles so I prefer leading with an instrument that
will be heard above the ambient volume of the group.
And, whereas ordering directly from Synergy meant a 6-7 week wait, my friend would
be able to ship the one he had in stock almost immediately
(email me and I will try to get you into contact with him -

Anyway, since receiving the Synergy Hybrid eKoa/CF Concert I have been using it
just about exclusively. I recently uploaded the first of a projected series of 9 videos
to YT of "Holiday Songs 2021" with pdfs for viewers so they/you can play along.
BTW I'm in Seattle and if feasible I would love to join you sometime. If you use an iPad
I will share/Airdrop some of the music I have in the GoodReader app
keep uke'in',
