I can say that there are a very few definite things regarding neck dimensions for me.
I tend to like and can play just about anything except for:
1 5/8 nut widths (too tight in the first 5 to 8 frets)
7.25 radius (my pointer has issues barring chords. I know, weird right?)
I prefer larger profiles in general, but shoulder size can offset a thinner neck for me.
From '97 to '17, I think I only played 1 11/16. I didn't know about 42mm, and 1 5/8, well.......
Then I got a few ltds with 42mm nuts, and my world didn't implode or anything. Lol they're cool too. I may actually prefer it now. It's hard to gauge unless you try the same guitar in multiple widths.
My first 2 warmoths necks were 1 11/16 (fatback 1st, 59 2nd), but I reeeaaally wanted to try the boatneck.
Based on aaron's video that said nut width affects the profile significantly, I wanted to err on the smaller side, and went with 42mm. I'm not sure how much difference it makes in the profile, but I am glad I went with 42 instead.....I think.
I would have no problem going 42 from now on, especially if it means the profiles are slightly smaller.
What I can say is that hindsight is a bitch. Back in '97 I went back and forth between boat and fatback. I shoulda done the boat back then. All the talk of a v shape scared me off, i think.
While I like all 3 profiles, the boatneck is fast becoming my favorite. The 59 was my fave for a decade, but now it is starting to feel a bit thin. The fatback now feels a bit too shouldery.
I think profile shape and overall size matter more than nut width for me, unless it's 1 5/8", which should be killed with fire. IMO, of course
