My neck profile is a soft "V" profile on a medium chunky neck (.89 at the 3rd fret), an 1 3/4th nut with wide string spacing, rolled fingerboard edges and medium jumbo frets with a modern 12 inch radius. I'm always looking for the best ways to make my necks "disappear". Current (2010) neck backs are satin nitro lacquer for a silky feel right away, no break in needed. The headstock and maple fingerboards are finished in gloss nitro lacquer and it's always applied directly to the wood in thin coats. My finish process is different from most, I apply thin coats over a generally longer period of time to allow the previous coats to sink into the wood and gas out. This method helps me apply just enough finish rather than load the wood up with lacquer. (The same process applies to bodies).
The 1 & 3/4ths inch wide nut w/ wide string spacing and soft V neck dimensions blend together for a fast neck with improved string control. Fingerpickers and flat pickers appreciate the extra real estate with extended string spacing I use at the nut.
Acoustic players and fingerpickers find my necks fast and comfortable. Again, the best neck is a combination of the right specs that work together for comfort and easy of playing.
