For the first one I was using a 5/6 fiberglass rod- I thought it was going to break! It did hold up well and the action was beneficial for the head shakes. The second was caught on an 8 wt, while it was still doubled over, it had significant (as you would expect) more backbone.
Sweet! I just started chasing them a bit on the Colorado out west. Have yet to figure them out and connect with one, but have seen decent numbers and some big ones that would be fun to catch. Rocky mountain bone fish. Sight casting is always fun.
