Very true, in many cases people will state that it may indeed have the best say, neck for instance, but if the string spacing just isn't you or any one of a dozen other things then it's gotta go. I'm sure the basses I still have of the 50+ I've owned have none of the single best features, best body was a green status, best for slap was a Warwick etc but it's the getting one that's just the right mix that's tricky.
And trust me, I've often often had to sell things I really don't wanna sell. :-D
