If I wanted to buy a new std class ship I would buy the one with the
shortest delivery time.

Discus can offer...very roomy cockpit (by far the largest), nose-wheel (vs tail
dragger) for better x-wind performance; tough landing gear (same as on a Cessna
150)--check out particulars @www.groupgenesis.com

LS8 for 3 years (280+ hours on it) and raced a Discus 2b recently for 40+
hours. Some of this was with a friend who was flying an LS8. Both gliders
were less than 5 months old. We were both flying as near to 525kg as we
could measure. The only real configuration difference was that the Discus
2b had bugwipers. Both had tailwheels.
My experience was that the LS8 consistently outclimbed the Discus 2b - but
not by very much - (some of which I will allow may be my relatively
inaccurate flying) except once where I had dumped more water . . . The
Discus 2 seems to need to fly faster (120kph) in a circle with water than my
LS8. Anything less and it was starting to mush. This may have contributed
to the (ever so slightly) poorer climb rate.
I detected not much difference in the glide at a range of inter-thermal
speeds. I thought the Discus 2b had a larger performance loss than the LS8
with wet wings and I have the impression that the LS8 handles 'unbalance
flight' situations (turns, pull-ups & pushovers) better than the Discus 2.
I didn't do a precise timing but I felt the Discus2 to be slower - again not
by much - in the roll.
Some other points:
The Discus 2 wings were definitely more difficult to rig. I prefer 2
mainpins so you can see how the line-up is working.
I dislike the fact that the LS8 wing is unprotected until the tips are on
(not a problem with the D2). You should also note that both gliders suffer
from large areas of low wing clearance when the wing is on the ground & this
results in more damage & maintenance (the Discus 2 has a larger exposed
area).
I could not find a way to stop water drips leaking from the Discus 2 (for
all the vaseline used). Also the watertank filler caps didn't fit flush.
I'm sure these could this could have been rectified if time had allowed.
The Discus2 certainly has a much better dump rate than my LS8 (even after I
drilled holes in the upper surface of the LS8 to assist venting (the factory
fresh ones are better now).
To retract the wheel of the Discus2 requires a pushover in flight (<1g) and
on the ground requires a second person to lift the wheel (1 man-rigs will
now have to come standard with a mainwheel jack!). I expect the factory
will mod this shortcoming sooner or later.
There is more baggage room in the Discus2b than you can fill and still be
under max all up.
The Discus 2b has better cockpit ventilation than my LS8.
SUMMARY:
To be honest, the difference in performance between the two is so small that
it will be completely overshadowed by the first error you make on a cross
country flight, so don't expect that choosing the slightly better of these
two will give you any leeway to make mistakes . . the weak link is . . .
the bit the Germans didn't design the hell out of . . . sitting behind the
stick! And the best way to improve that bit is to quit the keyboard & get
back in the cockpit. I certainly felt that the relative difference in
overall performance we recorded was a reflection of how the pilots performed
rather than the kit.
Don't waste too much time deciding, both are a privilege to fly. Buy, and
fly, fly, fly!

Thanks Alan and Kathryn for that very detailed information.
There is one thing which I recognized this year during a competition in germany.
The LS8 climbs in rough air a little bit better that the Discus2. And in a
competition even a very small performance difference could have a great
impact...

Now that's a worry!
How do you make sure you don't get a Monday glider?

back for corrections to the factory several times. He finally sold
it frustrated and bought a ASW-27!
Is the quality not the same anymore as it has been under Klaus regime?

Monday gliders happen in any factory. There are no gliders that are
the same. The quality has not changed since Klaus's regime. Gerhard,
does not have to worry about quality control at Schleichers and is not
responsible for cost effective production. Thats Edgars job.
I have seen the most adiment Schleicher pilot who has flown nothing
else in his life switch to Schempp's because he found it suited him
better.
There is so little difference in the gliders, performance wise, these
days that it basically comes down to personal preference (oh and the
world comps results.. )
I have seen an undercarriage break out of a 27 at the Kingaroy
Nationals. Has the quality changed at Schleichers too?
