For 25 years I was playing a Fender Precision with an A neck. I had no idea it wasn't a "proper" Precision neck until the Internet came along!
For the last 25 years I've been playing 5 string basses, all apparently just under 2" wide. I've never bothered to measure a bass neck until threads like this started up.
We're all different, but looking back, going from very thin necks to extra wide necks has not been an issue for me.
