I am inclined to agree with warren, though my experience with which planes are actually capable of feeding with the iron tuned and set properly has been less than stellar (especially in regard to late 19th and early 20th century wooden planes, where the second iron is in horrible shape with its original milling marks, i.e., there was much work left for the craftsman in terms of bring the second iron in to shape).

Cheap metal bench planes with standard chipbreakers have been fine, though, at working anything I've worked in any direction without tearing out like they would if the iron wasn't properly set.

Convenience still has me leaning toward a single iron, steeper pitch and a tight mouth, though, but planes of that quality cost money or time (i've spent the time and money already though).

How does one set a japanese chipbreaker that tight? I can't see well enough down into the mouth of my japanese planes to actually set them as precisely as they need to be set to do that work.
