i voted "new neck."
Which is why I'm so glad I started with Peavey when I started back playing. I quit at thirteen and started back in my middle thirties so I essentially started from scratch. I got my old bass from my dad and it was in such poor shape I went looking for something else. I wound up with a T40 needing some work so I took it to a local Peavey dealer to get it looked at. While there I tried a Foundation. It was nice but I had the T40 and I was lined up for lessons so I just got the (minor) repair done and went to the grind. About a year later I got a side job rebuilding a Sportster engine and it paid enough to allow me to add a little mad money and get a low mileage Foundation. A week later I traded the T40 for an old Bassman head, and was a dedicated skinny neck geek for the next fifteen years. Five years in I ran across a brand new Fender model, the Jazz Plus. In addition to being the inspiration for the Warmoth dinky jazz, it had a neck so slim I was first concerned about how long it would last under tension, but it played so fine I took a chance. Thirty three years later I've still got that J Plus. I've branched out to current C necks on MIM J basses, but every time I play the Plus, I wonder why I bother with any other bass.
Sadly, time and abuse of my hands have forced me to go to short scales as I learn to live with a non functioning pinky on my fretting hand. I'm offloading all my 32" scale stuff, but so far I've managed to rationalize keeping the Plus.
