I have and liked the 40 lb. What are you comparisons to the 30 as far as Tangles go? Would 30 lb be a good choice for 5 wt rods and under? Do you have any concerns with the spectra cutting the loop on your head?
My new favorite rod for the Clearwater is a Walker 16’6” 8/9 with a Boss long 8/9. Before that it was a Steve Godshall 16’7” 7. My first CW Rod was a 14’ 7/8 with a GF 54.
