Following the recent discussion on woodie smoothers,
esp WRT steeper pitches
(consensus seemed to be more effort, less tearout)

Following the "opposite" logic,
would it make sense in a woodie scrub to drop the
angle a bit (say 35-40 degrees)

You can't go lower than that because you need relief for
the blades bevel.

I know the venerated #40 is 45 degrees, but I would take that
as more of a "production" decision than a design one.

Comments?

I would not go to a shallower angle on a scrub plane.  The cutting edge of
the scrub iron takes quite a beating.  A 45deg bed angle allows for a 35deg
bevel on the iron which is tough enough to give good edge life.
