You're quick with this answer, and I suspect it's based on experience,
but it seems a bit counter intuitive to me. I can see that only
shortening a little would make little difference, but I wonder how
losing the strongest fourth of a rod would leave it's rating unchanged.
I also think it would make quite a difference if the rod was fast
action or slow action.

Do you have any links to sites that explain how to calculate the rating
for a rod? I'm expecting there should be some formula based on the
static flex caused by a standard weight for a given length.

Shortening it from the tip end will
do so, but there is no way of knowing by how much, except trial and
error.
This is not advisable.

I'm with you there. We have an 8wt Sage RPLX rod that lost about a
foot off the end. It casts a 10wt fairly well, and my son Andy uses
that tip when casting a float and a couple heavy split shots for
steelhead with his 8wt line.


If you want a short #8 wt rod, then buy a nine foot #8 wt, and shorten
the
butt. Actually, I can see little point in this. A nine foot rod is
generally more advantageous than a shorter rod.

Let me ask for a bit more of your experience here if I may. If the 9
foot rod is "generally" more advantageous, when do you think it might
not be advantageous?

Thanks for your help,
