I have a regular neck on my Mira Korina. It is such an easy neck to play. I had a wide-thin neck on my ‘11 one-off CU24. That guitar was beautiful, but I never bonded with the wide-thin neck. I have a McCarty 58 with a pattern fat neck that is a handful, but it is smaller than the wide-fat neck that I had on my ‘95 Standard 24. What is interesting is that the ‘19 CU24 I purchased earlier this year has a pattern-thin neck and I find it to be joy to play compared to the wide-thin that was on my CU24. It’s not quite as comfortable as the standard neck on my Mira with the standard baseball bat, thumb over the top edge of the fingerboard grip, but it is significantly more comfortable than the standard profile with the thumb on the back of the neck classical grip. I can play significantly faster with the classical grip (not that I am any kind of speed demon).
I could live with a mahogany back. That way, the back would be one piece instead of two or three. However, the guitar would have to have a set quartersawn maple neck, McCarty switching, and Gen I bridge, which means MannMade NOS today.
