I noticed one of the Infusions at Weston Sailing Club having it's slots filled recently, the owner told me that 'all the top guys are doing it' so there is probably something in what you say. Where are you based btw?
Paul - did you notice your failing boards when your fancy dancy gadget trapeze adjuster dropped you in the drink on that calm day at Pevensey? I've never seen a crew looked so scared and I can still hear her screams today......
