A good person to ask might be Kolie (skylinesoaring.org) -he just moved from a
LS3 to a Diana 2. So far I have not heard ANY complaints about the Diana's climb
performance.

In gusty conditions, the climb rate can be improved by thermalling a
bit
faster, so this region is avoided (gusts can't increase the AOA
enough
to enter the region). Because the "flat spot" is wider in the
thermalling flap setting and diminished or not present with more
negative flap settings, using the neutral flap setting in gusty
conditions will also avoid (or at least improve) the situation.

I've had my Diana 2 almost two years - moved up from a 304cz. The
Diana 2 has climbed
out of valleys late in the day that would have swallowed the cz.
Remember the Diana is 25 years younger
(and how many generations?) than the cz... The 304cz is a great glider
and I loved mine dearly. When the
lift gets strong and bumpy here in SoCal, one needs to speed up to
maintain control anyway.
As I said in an earlier post, and Wladimir expanded on, it isn't just
the airfoil that determines climbing performance.
