Ardent that is one beautiful rifle in just about every aspect. As far as the checkering question goes - to my eye an uncheckered stock is just "not finished."
My only suggestion would be to go either "semi" flat / "absolute" flat. The absolute flat hides non of the grain, the good thing is if go absolute and
don't like it you can go to semi and even pointed. Doesn't work so well the other way around.
Should anyone want to try absolute flat, I can forward you a pic. of the cutter involved by Email. You will / can still use your spacing & border tools etc.
