What do you guys think about that method Robert Randal wrote up in the Journal of Light Construction, maybe 8 years ago or so? The one where he would glue and screw a 1" x 4" (or maybe 6") the full length of the underside of the each joist, maybe even pre-stress it mid-span. Claimed if I remember right that method would effectively reduce deflection equivalent to increasing to next larger lumber size (i.e. in this case taking a 2" x 10" to a 2" x 12").

I only remember the article, never did anything with it, nor have I ever seen any test data to support his claim.
