You are correct about 270ktas for the Saab. To factor in a slower climb, 235-240ktas average is a better figure for planning. That would make it just under 2hrs flight time. Block time will be slightly longer, as per usual.
From memory you could bank on 182KIAS in High Climb, equating to 180-200kts GS.
Can't see a problem unless a tempo gets slapped onto the TAF.
