I have only played one F and no FTC.
I love how the F just puts right back out what you put in. I think a punchier archtop sound for it would be welcome though, it was too small for a pick and seemed down on power.
I think FTC also suits your commemorative philosophy on a really high level, it’s also kind of the fancy Santa Cruz on the block for the past few years so it suits the timeframe now as well. It would showcase the best work of the shop better since it’s construction is what it is.
Having said all that both would be awesome!
How about sharing your perspective and emotions regarding the choice? The F I played I think was sitka and rosewood. It was very much asleep on the wall of a guitar shop.
