I like Sage rods and have a closet full of them.
The TCR and TCX are a specialized hybrid of rods.
I played with the 590-4 TCX a little and then put the 5wt long belly line on a 790-4 Z-Axis, they are similar in casting with the Z-Axis being lighter in the hand (swing weight) and more comfortable to cast. The TCX has a stiffer tip than the Z-Axis or XP rods.
Many eastern FF like the 490-4 TCX and TCR in windy conditions and longer casting opportunities.
My favorite and only rod of this category is the 10150-4 TCR, if the line in under your feet on the presention cast,,,,, it upend your butt.
