cross polarization and data backup questions

Greetings Bruker users:

We have a Bruker Avance 600, and I have a colleague who wishes to do
some 13C-1H cross-polarization experiments on gel-like samples [e.g.,
Sutherland et al. (1979). Biochemistry 18:1797]. Specifically, I need
to do a 1H-13C cross polarization experiment with 1H dipolar decoupling
using standard liquids amps and probes. Since the original experiments
used solids equipment at 1.4 T, I imagine some modifications in
procedure are required for work at 14 T.

If anyone has (or can point me to) a suitable pulse sequence and dipolar
decoupling pattern, I would appreciate the help. Since I've been doing
solution NMR for the last dozen years on V* spectrometers, I'm a bit out
of my element here. Any helpful comments in general would also be
appreciated.

In another vein, we're considering different mechanisms for user data
backup. Can anyone offer comments regarding CD-RW or Zip drives as
useful backup mechanisms? Are data cp'd to a Zip readable on
PC/Mac/Linux platforms?

Thanks for any help.

David A. Horita
