My opinions are based on a very short experience of hands-on.
For the most part, with the fret wire I've handled, I thought it was.
You know it goes through quite a bit of abuse even using the press
rather than hammering.
Mike I do know that if the neck/fretboard is worked to a precision
level that it is very possible to require minimum fret work.
The biggest bummer I've seen after working a fretboard to "perfect"
flatness (just beautiful when checking with a precision flatbar) was
a section of the fret wire that didn't have a uniform crown height and a
couple of the frets were lower than the rest.
When dealing with thousanths of an inch when leveling the crown one
can understand not being able to detect the variance by sight when
installing.
With that said, precision crown height and width could sure save some
aggrevation. One doesn't enjoy having to remove a fret and possibly
chipping a fretboard.
I think I was reading about Heritage guitars and they had a press that
pressed in all the frets in one shot. Man I'd like to see that. Frets can
tilt or roll while inserting the tang in the groove and for them to press
all of them at once...I'd like to see how they prepare them before the pressing.
It seems to me that one pressing for all of the frets would be the ultimate method.
That method with precision wire and a well made board...very cool and I
believe those guys designed the press and may be the only ones installing
them like that...but I don't know.
More coffee.
