Havent really found much info on these, so thought I'd put something up myself.
Ive tried the IQ, Gaastra's 4 batten now in the 5.4, 4.7 and 4.2 and so far I can say they are the first sail I'm really happy with. More stable than a fly2. A very compact strong sail but still incrediably light in the hands, which for me is what I'm after while trying things. Also works surprising well overpowered, doesn't get backhanded etc or twitchy with alot of downhaul... Fairly grunty in the nuetral setting but flattens off well. Basically just easy to sail, so you can concentrate on that new move rather than wrestling with the equipment.
I think the 5.4 is an ideal motor sail for that 15kt down the line stuff, where the you need grunt to get out but still want a smallish sail.
Looking forward to the NW trip.
