Seems like the majority of issues people have mentioned with warmoth necks (thickness/weight) would be directly addressed by this newer profile. Slimming it down would help with the weight some.
I disagree.
I've never had issues with the thickness. I liked the shape of the two Warmoth necks that passed through my hands: (Maple/Ebony, All-Maple). The thinner profile would be nice, but I doubt it would effect the overall weight.
It's those pesky steel rods. Both of my Warmoth necks were 10-12 ounces HEAVIER than, say, a stock fender neck from the 70s. (that's 3/4 of a pound heavier, kiddos). It doesn't make too much difference on a nice heavy Fender (my '79 Jazz weighs almost 12 pounds, so no trouble there), but if you try to build a bass out of Swamp Ash or Alder, forget it.
And it's not just the weight.
The rigidity of those steel rods takes all the character out of the sound.
I'll never forget the first time I swapped out a Warmoth neck for a USACG neck on the same bass. The sonic difference was night and day. Tommy (USACG) uses graphite instead of steel, and you can feel the notes. The bass sounds warmer, notes have more "bloom," whatever you want to call it.
I tried a Warmoth neck on my '71 P-bass and it just sucked the life right out of the bass. Turned it from the best sounding bass I have to a generic, soulless doorstop. I think that neck was on there for about 7 minutes before I put the original (warped, beat up) neck back on. I'd rather fight for a good sound than effortlessly get an anemic sound.
What frustrates me about Warmoth is that they offer 100,000 options for guitar necks (compound radius, 8 custom back contours, vintage construction) and they don't offer any of those options for four string bass: Two back contours (now), two nut widths, one fingerboard radius (10"). That's it. Why can't I get a 7.25" radius Jazz neck with a U-shaped back contour? A compound radius? Vintage construction? Why are bass players second-class customers?
(I know, I know. They are trying to eliminate dead spots, and they want to be able to warranty their necks 'til after the apocalypse. And they're running a business. Volume, volume, volume, least common denominator, etc.)
I'm not a Warmoth hater... I
want to love Warmoth. I desperately want to love Warmoth necks. The necks in their "for sale showcase" are gorgeous. They get amazing woods. And I do love their bodies. I just wish they would get rid of those damn steel rods.

Dear Warmoth,
Offer me a vintage construction bass neck with no warranty. I don't care. I know it will warp eventually.
OR OFFER GRAPHITE RODS. I know it says on your website that you tried graphite before steel, and there were still some dead spots. BIG WHOOP. My Fenders are rampant with dead spots, BUT THEY STILL SOUND GREAT. I'll take the risk. I know there will be dead spots. I'm a big boy.
I know the "super bass construction" necks will last forever, regardless of temperature and humidity changes. But it doesn't matter how long they last if I can't stand how they sound. Make them out of solid brass! Stainless steel! Carbon nanotubes! Then they'll NEVER warp!

(To be fair I
can actually see some cases where the super rigid necks would work: for a fretless perhaps, and maybe for really dense (heavy) bodies if you're going for more of that "piano" tone.
I just wish they would offer steel OR graphite AS AN OPTION. Why do guitar players get to have all the fun?)
