Dan,
Don't quite agree about the Rallye. I regularly fly a 150ST, which I like a lot.
But.... it'll only take 3 people with full tanks (5 hours safe endurance, cruising at 90-95kts), is uncomfortable in the back due to the wing spar taking up all the foot space, has no baggage compartment, is limited to +3.8g and only has lap straps - which rules out aeros.
