I have not tested the 3m yet and I don't hydrofoil. They are 2 others French riders on hydrofoil with a 4.5 and they are quite enthousiastic about it. Our opinions are very similar after testing >> http://www.lesfoilz.com/phpBB3/viewtopi ... 8&start=40
I had another session on the 4.5 on Monday. Nice swell at the beginning and messy when the wind switched to mistral direction. Wind was 25/30 knots with lulls just above 20 and gusts close to 35 knots. Wind was quite strong and gusty at the end of the session and from on-side-on to side. It is really a very nice kite, very solid in the air and very fun. I was very comfortable in the gusts. Great high wind kites for wave riding. I had it in the water and relaunch is a formality (I had it in the water at the end of the session in small waves - in big waves, this will be more of a hit or a miss as with any kite but relaunch in small waves is very easy - I would say easier than with a LEI).
