VB's right - wood names can be confusing, misapplied or simply changed for marketing reasons. For example, we can start with black or (white) Korina. There's no such thing. It's actually black Limba. I can't find the source now, but my understanding is that Ted McCarty (Gibson's CEO in the late '50s, early '60s) named it after his daughter, Korina. I don't remember why calling it by it's proper name was unacceptable. Gibson used that wood for their "modern" design guitars in the late '50s - the Flying V, Moderne, and Explorer. Everybody's been calling it Korina ever since.
Another one is "Flamed Maple". There's no such thing. It's
curly Maple. Go to a lumber yard and ask for flamed Maple, and unless the guy you're talking to is a guitar player, he'll look at you funny. "Flamed" Maple is a finish I think is also credited to Gibson, where a body with a curly Maple face is dyed yellow, then gradually transitioned to red at the edges and finally clear coated. When you move the body in the light, the natural chatoyance of the wood makes the curls seem to move, sorta giving the impression of a flame...
They sometimes call that a sunburst finish, too, for its resemblance to that. Today, it doesn't matter what color it is, including clear. If it's curly, guitarists call it a flame. Same with the "bursts". Doesn't have to look like the sun; if it transitions from a light center out to darker edges, guitarists will call it a 'burst.
As for your body's "plastic" feel, that's because that's what it's finished with. Or, more accurately, polyurethane. They grain fill the wood first with a polyester compound to level it out, then the urethane goes over that. Once it's buffed out, it's a very glossy and very level surface, so there's no woody texture to it. It's what all the manufacturers use these days, as lacquer is a very time-consuming finish to get right. Another benefit to the urethane is its durability. It'll take a helluva lot more abuse without showing it than any other finish. It's also impervious to most solvents and liquids, and won't fade or shrink. With the proper chemistry, finishing can be a one-shot deal, where they shoot it and hang to cure, and they're essentially done with it. Nothing else comes close to its combination of beauty, utility, ease of application and low maintenance requirements. Unfortunately, polyurethane as a guitar finish developed a bad reputation in the early years of its use due to the way Fender was applying it, which resulted in a very thick finish. While it didn't/doesn't matter on electric guitars, no "real" luthier would use it on acoustics due to a fear of its possible vibration damping quality and the resultant tonal deterioration. The "bad tone" word spread without the acoustic vs. solid body distinction though, and and even today you'll hear guys pooh-pooh the idea of putting a urethane finish on any guitar. It's a silly, undeserved reputation, but there it is.
I don't know what quality issues you have with your body, but sometimes people are surprised to see "fuzz" in the cavities, or maybe even some polishing compound residue. Cavities don't get any attention from the sanders, so when the finish goes on any wood fiber will show up more and feel rough, and when it gets buffed out sometimes that rough surface will catch fibers from the buffing wheel. If there's anything more than that, you should take it up with Warmoth. For what they charge, you are to receive a very high-end body. Anything less is unacceptable to them as much as to you. They have a reputation to uphold, if nothing else.
As for a neck recommendation, you can still go high-end without spending a ton of money. Do the black Ebony over roasted Maple I mentioned before. Trust me, you won't be sorry. That's a
great neck combination both in appearance and playability, and it won't break the bank. Plus, it'll look fantastic on that body.
I hope that calms you a bit - I thought you were kidding earlier about your dissatisfaction, or I'd never have gotten flippant about it. I thought I was just playing along with what you started. Sorry about that.
