Hi Stage 1;
I live about 10 miles from Little Ossipee, I haven't fished there in over 10 years. I know there are Brown Trout, Togue, Land Lock Salmon, Black Crappie, Yellow Perch, Pickerel, and some Large Mouth Bass. But I have never heard of any Smallmouth coming out of there.
If I were to troll on that lake I would use tandem hook streamers, on lead core line. Just a thought. Any Carries Stevens type Rangley fly should work.
Flies I would try;
King Smelt
Black Ghost
Arnold
Nine Three
Govenor Aiken
Mickey Finn
Montreal Whore
I hope your friend has a great time, and caches his share of fish.
