You can maintain a more even overall string height, which can also be lower, and you'll be able to bend notes and apply vibrato without deadening or fretting out. It'll feel very natural to you
I disagree with all of the above but only based on my "personal and subjective" needs.
Although the 12-16 compound is ok ... tolerable ... to me ... ( I have 2 of them )
I'll not ever be getting an other.
My last purchased Warmoth neck is a straight 10" and is much more consistent across the whole range of the neck.
No bending on the straight 10" ... it's strung with nylon ... but it's the most consistent feeling and playing Warmoth neck I own out of the 3 ... the other 2 are compound 12/16, and all have the same fret size.
I've had many Les Pauls in the past and still have 1 G&L with straight radius that have a more consistent string height and feel across the whole range of the neck than my two 12/16s.
The compound radius makes consistent string height impossible and a consistent feel across the full range of the neck also impossible in my opinion.
I've never had an issue with noting out with straight 12" radius necks and that includes bending notes up to a major 3rd or even a 4th at some times.
BUT ...
I don't like extremely low action and always set up my guitars for a somewhat high action.
For me higher action always translates into more sound ... more string excursion ... more dynamic range ... and above all ... much easier to play and faster playing.
When my action is too low it always slows me down and make for more physical effort.
I'm not saying anyone else is wrong in liking the compound 12/16 or in liking a low action.
I've just found that I have different preferences.
