The point is to get it close. A big old heavy reel may overbalance things while a supe light one my not be enough. Again, we are talking tenths of an ounce differences for most blanks and what line is out which should be negligible to the "feel" of the rod. There is wiggle room in the variables and equations.

One of my customers loves the rods I have built him on American Tackle Matrix blanks and fishes them much more than any of the Sage or Winston rods he has. The Sage and Winstons are certainly lighter but the Matrix rods are "more fun". He has the skills to handle a super fast rod but has "more fun" with the medium fast action Matrix.
