Is a 1-piece neck on a 5-string stable?

My AB I 5str has a 1pc neck and has no problem

Ok... I am going to go ahead and make this one a player then. I just sent it back to PRS to have the BRW ramp added (PRS customer service is incredibly good). The ramp will have a radius to match the fretboard. Then, I am going to have it PLEK'd with a heavier set of Ken Smith round wounds - since the brass nut needs to be adjusted anyway.

A one piece neck should be fine I recon.
Mine took a little time to settle but now it's happy with the 46-126 5 string set I put on.
I sometimes use 40-120 as well.
I prefer the tone of one piece necks.
I think you don't have much to worry about with your neck.
Mine however is not heavily figured, just a light flame.
When I ordered , I specified plain maple with no figuring, for stability reasons.

it'll be fine, or..................take measurements now and put em in the case so 35 years from now when it's a little twisted or bowed and the frets won't stay in the slots (because you've had it refretted 5 times) you can replace it with a multilaminate/multitrussrod outerspace material.

I read recently that Roger Sadowsky swears up and down that figured maple isn't stable enough to support string tension.

I had a repairman tell me essentially the same thing about the 1-piece bird's eye maple neck on my Schecter B/4: He said "pretty woods like this are fine for body caps, but they're not structurally robust enough for something like a neck."

On the other hand, I haven't had that bass set up in over 10 years and it still plays like buttah...
