I love these types of quizzes so I couldn't resist.
disclaimer: I can't adequately perform any of these casts and I have never fished for Atlantics BUT given the opportunity I would -
1. Follow Peter's advice and move up 20' to 30'
2. tie on a surface fly like a Waller Waker or something with a rifle hitch
3. use a single spey and get that thing skating on the surface just ahead and over those fish to try and entice them to follow and take on the surface.
4. if that didn't work I would then repeat the single spey with some Atlantic wet fly and try to get them to chase a subsurface fly
