Back at home, here's the report: The 6-7 rod with 6# line & 4x tippet was major league fun with the bones. Didn't get to fish as much as I wanted, but hooked six and landed(and released) 4 in the 1 -1 1/2 pound size. First one hooked broke me off - put the brakes on a little soon. The rest ran my backing down quite a ways. Not much drag on a 6# rated fresh water reel. Last one ran at me too fast to keep tension on the line - couldn't reel fast enough, and it spit the fly at my feet.
Lots of fun just wading the windward side of the island. Crazy Charlie pink/white/flash shrimp pattern caught all the fish.
Thanks to all for your advice.
