   How about overall weight and center of gravity location?

   Beebe—I just posted something that might be of interest (of course, by the time you read this, you’ll likely have already the post).

   Yeah I just saw that. Experimentally determining inertia moments can be difficult, and center of gravity location alone tells you nothing about MOI.

   I was wondering which made a rod more tiring to use:

   1. Tip weight of the rod forcing your wrist to keep the rod angled up
   2. Overall weight-in-hand of the setup

   I weighed several of my rods to get an idea of overall weight, and then I balanced them on the trigger/reel handle and put the scale under the tip to get an idea of tip weight. All of the tip weights I measured where very close to each other, even for heavy rods. Granted, I didn’t do a very scientific job, but I was just after a rough number.

   This led me to the conclusion that weight-in-hand is more noticeable than a rod with a slightly heavier tip. I’m not sold on this idea yet since I’ve never bothered to counter-balance a rod by adding weight to the butt, and I never followed up with more careful measurements of tip weight.

   I do not think that the problem is really weight or that adding weight to statically balance a rod is the solution. I think that the problem is actually mass and the inertia that is a result of the mass.
   If weight is added to statically balance a rod the rod is only balanced while it is motionless. The instant that the rod is put into motion then the inertia will put the rod back out of balance and most likely make the situation worse then if weight had not been added.
   It seems to me that the only solution is to build the rod as light as possible to begin with.

   I agree.

   After looking through the MOI pdf’s I dont think you can do much about inertia, thus reducing weight-in-hand is about all you can do.

   All rods are built about the same way, and tapers and materials dont vary enough skew these results.
