The Blues hit the 50-point jackpot in Edinburgh, gaining a bonus point in their seven-try demolition of the Gunners.
Coach David Youjng praised the performance of his side, saying:
"This was another positive display, very similar to last week's against Sale. We played into a gale in the first 40 minutes but were still 22-10 ahead at the break. If anything, we could have had even more points on the scoreboard. Our build-up was great but we tended to rush things when we reached their 22.
"That all changed in the second half when we showed top drawer skills, with our off-loading in the tackle particularly effective."
