Grasshoppers got their heads around the RFU's new Experimental Law Variations in a pre-season tournament designed to hammer them home on Saturday.
The ELVs, which propose changes to the laws governing scrums and mauls, lineouts and penalties, were given an airing at the event in Barn Elms.
Hit by injuries to a string of senior players,Gs took a young side, including a dozen lads aged under 21.
And the young guns did not let the side down.
After a draw with London Scottish Academy, Gs thrashed Weybridge Vandals 24-0, with young fly-half Tom Orishaguna in total control.
Four 18-year-olds, namely Korede Okelana, Ciaren Clement-Pascal, Jon Royer-Harris and Wajim Said, were instrumental as Gs then battered Battersea 17-0.
And in the final game,they edged out old rivals London New Zealand 12-7, with Steve Reffould, Joe Ravono and Matt Nemeth running the show.
The Second XV lost twice but beat Old Millhillians 17-12, with young wingers Tom Dixon and Darius Jafari both bagging tries.
Gs director of rugby Matt Gilmore said: "We came here today with several experienced players missing and replaced them with colts. "Our goal was to blood several of our youngsters and play good rugby under the new laws, and I'm happy with what
I saw. "All our guys showed great desire and commitment, and I'm confident once our injuries clear we will have a strong squad to compete in London
Three. "And with the seconds playing well too, it is evident we will have a strong young squad with a real competition for places."
