You could also try seeding, crush up your needles seed a new plate and
re-screen. With re-screen I mean not your original conditions but e.g.
Hampton 1&2 or orthers and see if you get a different condition with
other crystals.
You might also see into your current condition. I assume you have
screened for pH already (not only using the buffer which is in your
current condition).
Good luck,
Jürgen
P.S. Besides are the crystals mountable and >5 µm thick why don't you
go to SLS or ESRF and collect data there ? Thick does not necessarily
mean better.
