Well... I've got this far, I think I'm going to go all the way. The HB neck is 14" radius (or more accurately 350mm), which is a little flat for me. Also I'm getting a bit OCD about the headstock, as I was a bit too, er... enthusiastic in the reshaping. The whole thing is about 1mm too small all round...
This isn't about budget basses any more - if I replace the neck it really won't be a Harley Benton. I think I may go for a Northwest Guitars one-piece maple neck (9.5" radius), they seem to be great value... and take the opportunity to change the finish... again.

I thank you.
