Glider Choice at Argentina WGC

Club Class:
Used to be the case that the Cirrus / Libelle / LS1 / ASW15 level of
performance was the way to go. But more than 2/3rds of the field are now
flying higher performance ships (Taking the hit on handicap of course).
Wasn't the Club Class originally intended as somewhere for the early
(cheap) glass to find a competitive home?

Do people think this is a good trend?
Is this just a consequence of the expected weather in Argentina?

And yes I do know that the current leader is flying a Std Cirrus

Std Class:
The perception (here in the UK) is that the D2 has the edge over the LS8 in
strong conditions. However looking at the average speeds for most days so
far the conditions in Arg have been fairly weak so the LS8s should have had
the edge. D2s still seem to be dominating the leaderboard. Is this because
the best pilots normally fly in better conditions, and therefore own D2s
and are still winning despite the conditions?

Any thoughts?
