For anyone interested, I've avoided premium unleaded for the last ten fill ups and only used bog standard unleaded. I don't think that there is any difference for my Fazer between the two as far as MPG and power goes. I think someone mentioned that the engine needs to have a magical warp core device in it to make proper use of the premium fuels. I have noticed that with a full tank, the bike is more responsive though.
