Howard,
Max wing loading for the 13.5 Meter class in the WGC is 35 kg/m^2, so the Diana Versus and Mini LAK had the same wing loading as most of the Silents. They did it on less total area, so a lower total weight for lower span loading. Most pilots observed that the Versus, MiniLAK, and Sparrowhawk R all outclimbed the Silents, as they should, and the glider performance was also superior. I particularly noticed that with the Versus. I did not have many opportunities to fly with the Mini LAK. The Sparrowhawk R was closer to the Silent in glide but Morgan also has a fixed gear on his glider to be able to use it for Ultralight World Record attempts.
It is worth noting that once 13.5 Meter World Records are available (in October), there is no wing loading limit. So you might consider sawing down your 27
