The ride has been discussed at length, as you say, having sailed with them, I couldn't now imagine sailing without them! <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
Only update is the new Stealth (2006/7) T-foils are a fantastic improvement on the older ones. Small, lighter, stronger and much better engineered. Less drag IMO, but just as effective as the older, larger foils. John_P has done a really good job!
