Scott,
It is an interesting rod. I found it only slightly stiffer than the 9140-3, but that didn't take away from its very nice feel. In many ways they are similar rods, as I've always maintained, the 9140-3 is really a 10 wt rod this shouldn't suprise me. The 10140 may have a smidge more power but it has the same Euro action that I like for the dynamic snake rolls that are my primary casts. I have to say that if I had one of these instead of my 9140-3 I would still be very happy.
