Would you guys prefer the evolution of rod development remain in the 40's? Why is it everytime a manufacturer comes out with a new rod many of you dump on it? Especially one that is high end? I for one own many Sage rods and models and I like the fact that Sage continues to make improvement. I have noticed a big improvement from that of the SLT to the ZXL and the RPL to the Z-Axis, but not so much between the XP and Z-Axis. I hope they never stop coming up with new designs.
