He said: "We go in confident mood and have a strong squad at our disposal. Dafydd is our new face and he looks a good forward option at Sevens and we are looking forward to seeing him in action. He's quick, athletic and will certainly add to our options. We have a good blend and a good chance of being competitive at both of these home Union events."
Captain Edwards is also confident his young side can put down a marker at Twickenham and Murrayfield where they will face the likes of South Africa and Samoa over the next two weekends.
"We have a young team, but one who are very hungry to succeed and who are learning all the time at this level," he added. "It's important we go out there with all guns blazing and play with no fear."
