Hi Walsh,
its an SB1 5m from 2006. It has Switchblade written on the side, so I'm pretty sure.....

At the moment his power to weight ratio seems pretty close to mine on my SB3 12m and 135x40, I'm 73kg. In 12 knots he is just holding ground, flying a lot of S-patterns to keep moving. In 14-16knots he has the kite parked and is going upwind, and above 16 we have a bit of depower pulled on. Haven't really had him out in 16-20 yet.
Getting bucket loads of 12-15 knot shiite so far this winter on the island, it's driving the local crew nuts. Townsville seems to be getting a few more 17 knot days with a little seabreeze behind the SE trade. Have a new 8m that's been waiting to taste the water for over a month..........
Lizard next week for 3 weeks should fix that particular problem!
