Reprofiling LS6 wings

Is it standard practice to just reinstate the profile that
the wing had prior to refinish?

That's pretty much what you do. Make sure the wing profile is round in
front, pointy in back, and the waviness is below .004", and it will
probably be fine.

...Has anyone taken a profile from another aircraft to use, for
example using a later LS6-c to reprofile an LS6-b?

They're the same profile. Or at least the LS6-c left is the same as
the LS6-b left, and likewise for the corresponding right wings. I've
done template checks on several LS6 and a couple of LS8 to validate
it.

What about using an LS8 profile on an LS6, since they are
supposed to be the same forward section?

As you note, they're also pretty much the same, within the
qualifications noted above.

My advice: Don't bother trying to do a full profile job. The LS6 and
LS8 go like stink, generally fly very straight, and handle very well.
There is just about nothing a full profile job will do to change that.
It will defnitely add a bunch of weight and expend hundreds of hours
and thousands of dollars.

About the only things that would make much of a difference are the
leading edge profile back to about 15% chord, and getting the waviness
down to under .004". And my bet is that both of those are probably
already in pretty good shape.
