Keys missed out on a play-off place last season as an inconsistent run-in saw them just fall short of a top three finish.
And ahead of the new season, Keys will be looking to use the club sevens as a key pre-season warm up following previous games against Merthyr, Blackwood and Coventry.
A clash with the Ravens first up looks like an entertaining encounter and with both sides knowing a defeat will see them exit the cup competition, there will be all to play for.
"We've got a young squad but we're looking forward to the tournament," said Woods.
On his side's first round opponents, he added: "Bridgend play a lot of rugby in the 15 a side game so I'm not expecting anything different in sevens.
"It's going to be a challenge but in sevens tournaments it's vital to win your first game and take it from there. That's what gives you a bit of momentum to carry forward and you can take it from there.
"We've got some dangerous players but Jonny Lewis is a real threat and has got a good step on him. I'm expecting him to light up the tournament."
Cross Keys squad for Foster's National Sevens: Nathan Williams (c), Henry Palmer, Tom Lampard, Reuben Tucker, Jonny Lewis, Elliott Jones, Ciarran Driscoll, Darren Hughes, Dorian Jones, Ryan James, Aled James, Phil Williams.
