Getting wet downwind far to often

Had my new cherub for about a month now and seem to have got the hang of the upwind stuf, rarely binning it in (except with the obvious mega gust).  Our current problem is the downwind, the boat absolutely flies and have got to grips with the whole bearing away in gusts and heading up in the lulls to keep the power on.  The problem that i have is in the gybing, we appear to be binning it about 90% of the times we gybe in more than a force 3.

I know that this must be a technique thing and i've been advised the following two ways of gybing:

1) Head dead downwind then gybe one sail at a time jib, kite and then finally main - This has seen an improvement and manage to get through the gybe most times in a low 3 however when i flick the main and try to keep the boat downwind it seems to heel over and drop us in now matter how much i try to bear away with the rudder.

2) Gybe in a nice wide arc keeping as much speed up through the turn so that the apparent wind causes the actual wind to have less effect on the boat - Really can't get this to work, it seems to be how everyone else does it at the club but i seem to find that it ends up with the kite and main flicking at the same time and us getting very wet.

I'm sure that this is not a problem limited to the cherub as i seem to be able to bin in most asymetrics at the club (ISO's, RS400's, although surprisingly not my mates MX-Ray) if anyone has any ideas about where i'm going wrong please post and give me some hints.  Keep getting beaten on the water by a Mirror which is never good for ones street cred.

I'm not going to be able to make the week at Weymouth, i'm going to try to go down for the weekend before to try pick up some tips and stuff, aiming for next year if i can get the gybing sorted.

The boats capsizing to leeward, before my crew can get on the wire, just out of interest having the boom on the centre line (or just off it) do i let it out when coming out the other side or is this going to cause me more problems? 

Practice is always good just wanted to get the right idea in my head before practicing the wrong this if you get my meaning.  Thanks for the suggestions, will give these ideas a try, does anybody know of any good training routines that i can try?  Currently sailing to the top of the lake and gybing all the way back, any ideas? 

Main IN. It is NOT intuitive, so takes practise. Once you are planing fast, the main can be almost over the rear quarter. Gybe all the way round to the new maximum speed angle (no S curves as they are slow). Having the main IN means it has less far to swing. It also swings when the boat is almost dead down wind, so the boom crash is forwards, not sideways.

Forget the correcting S-curve, just keep turning to the new max speed angle. Keep the speed on for easy gybing. The kite must never collapse - it keeps the boat pulling forward and helps to prevent a capsize. Because you are turning to the new fast angle, you know where you need the weight - over the side!
