"The conference represented a meeting of minds from around the rugby world and some of the greatest and most learned men in the game have given their views," said Lewis.
"The top experts and administrators in the game have gathered in one place to debate and, most importantly, listen to each other's opinions, views and conclusions about the ELV experiment.
"The WRU along with all the unions of the world presented its research findings, Welsh voices were lead expertly by David Pickering and Nigel Owens, who is now regarded as one of the top referees in the game and, after two days, the conference has come up with recommendations which will be vital to the future of the game.
"Personally, it has been a privilege to hear the truly visionary insight offered by some of the great practitioners of the game from around the rugby world, by some of the great coaches and rugby experts who have such an impressive and intimate knowledge and understanding of the game."
