Please take my comments about Warmoth necks as my opinion only - there are plenty of satisfied customers out there.
After an unintended A/B comparison between a MIM Fender neck and a "Warmoth construction" neck on a MIM Strat, I think that the "Warmoth construction" with a double truss rod and an extra thick fingerboard sucks tone and clarity out of a guitar - especially treble.
Don't get me wrong, Warmoth makes good quality bodies, and I'm sure that the "Vintage Modern" and "Vintage construction" necks sound better. Unfortunately, IIRC you can't get a tilt-back headstock unless you get "Warmoth construction".
I'm about to start a carved-top tele style body, 1-piece mahogany with 1-piece rock maple top, mahogany neck w/ rosewood fingerboard in conversion scale for 24-3/4", tune-o-matic bridge, and Seth Lover pickups. The body and neck are from USA Custom Guitars. It'll take me months to get it completed based on past experience, but I'm hoping that it will sound very much like a Les Paul and possibly play as well or better.
You might consider a neck from USACG and body from Warmoth since USACG doesn't make an LPS style body. I'd thought about doing that, but a bolt-on LPS doesn't have much of a neck pocket compared to a tele or strat style body - take a look at the silouttes on the Warmoth site.
