Hello sean - I have that rod also, Pleasure to use, light in the hands.
I question to 9/10 skagit line rec, typo maybe? Here is info from 2 sources:
rod reccomendations pdf says 450gr skagit Tip or 600gr skagit float.
Airflow skagit specs:
9/10 is 650gr + sinktip = 750gr, 35' w/o tip, rec 14'rod
6/7 is 440gr + st = 520gr, 30' w/o tip, rec 12.5'rod
7/8 is 470gr + st = 560gr, 32' w/o tip, rec 13' rod
I would think that the 6/7 or maybe 7/8 is the right one.
Tim Rajeff emailed me after some questions and stated that the rod is designed for 450-475 grain lines (OH or scando, so skagit will be heavier).
After breaking a custom line, I used a 91011 windcutter w/out the middle section. wt=457gr
