Yup, it's a crazy world, mm, lol!
For the last UEL Ryder Cup I did switch flags (on Dazza's insistence!) but I think it unwise after all the kerfuffle around being honest about where you reside.
I am an ex-pat Scot, living in California. To me, the Ryder Cup is all about affinity, rather than residence, so it would be anathema for me to play for the US. Sorry! And Devon, early on, said his allegiance was to the US (but lives in Canada).
