I would
* Take the Double deckers off the X6 and put them on the X7, and I would take the singles off the X7 and put them on X6.
* reroute X6 to operate to Windygoul ( replacing the X44 and 26)
* Make the 106 every 30mins from Haddington to Tranent, then extend up to Prestonpans, replacing the 26 on that section.
While at the other side of Edinburgh, I would bring back the old Stagecoach 40/40A idea. ( Ie Lothian revised its No43) it's clear passengers in the ferry are getting a bum deal if people are still trying to catch Stagecoach express at the bridge tolls.
