Id love to see another Lions tour like they did in 1992.
3 tests vs Aus, 2 tests Vs NZL, plus GB played the club sides like Newcastle, Canberra, Parramatta, Illawarra and Gold Coast (I think Parramatta was the only club side that won, and Illawarra lost by a point IIRC)
Unfortunately it probably wont happen.
But with England and Wales playing in the 4 nations, doesnt really mean Great Britain are gone.
They'll bring them back in the future against Australia and New Zealand but only once every now and then.
Though I must confess to missing GB. when I was growing up it was always Aust Vs GB in the rugby league tests, and I thought it strange that England played in the union.
For a while I was thinking they were the same country. I didnt really take much notice in Rugby but it was cricket I used to think it was Great Britain.
Until 1995 World Cup when they separated.
