So I guess some options may be:
Tevita Kuridrani (eligible for Fiji now - experience would be handy acknowledging the number of outside backs they have)
Sefa Naivalu (eligible for Fiji now - provides a bit more versatility than just wing)
Chris Feauai-Sautai (eligible for Samoa now)
Joe Tomane I think is eligible for Samoa now?
Then there's a few 7s guys I wasn't sure of there heritage.
There may be others I have missed - I know Liam Gill, for example, spent a fair bit of time in the USA. But does anyone know if he has a parent or grandparent born there?
