I have a strat with one of the most amazing birdseye maple necks...
Its is so beautiful.
Alan can testify to the quality of this one..
It isn't as rigid 'apparently', but what Tommy @ USA custom suggested to me at the time, that we put two graphite stabilising bars in the neck.
Which I did...
And its an absolutely amazing neck still to this day...
Fits me like a glove and I cant find a more comfortable strat...
(closest feel to an E Clapton signature Strat) I like...
**insert graphite rods in here**
Hope my experience helps a bit
