Edwards was pleased with Wales' attacking threat but acknowledged that they will need to be at the top of their game when Andy Robinson's side arrive in Cardiff.
"It was a really entertaining game and a good advert for Northern Hemisphere rugby," he said.
"In attack we were excellent.
"We were slightly off the pace in defence in the first half after being on the attack for so long and we a little slow to get in line and we let them in for a try before half-time.
"But the lads showed a lot of fortitude and we came back well.
"We have played a lot of entertaining rugby recently. The conditions play their part in rugby but the brand is something you want to pay to watch.
"We had a day off and travelled back yesterday and today we will have our recovery sessions and then we will start the really hard work of preparing for Scotland."
"Scotland are another team that play entertaining rugby and Sunday's game against them will be played with the ball in hand."
