How are similar electrodes rated? Is one "better" than another? More stable for instance?

How can we overcome poor EEG signals when a patient uses an overabundance of hair gel or spray (despite our instructions)? We work hard to get great impedance values with these patients, yet still have unacceptable waveforms.

We have used the Piezo leg leads for some time and have been asked to change to the surface electrodes (2 per leg) per AASM recommendations. We have tried the ECG snap-on type and gold cups. We have 60Hz interference and are having trouble getting our impendences done. Do you have any advice on this?

What is the best way to clean gold cup electrodes do that they are cleaned appropriately and last as long as possible?

We run a pediatric sleep lab and our leads can take quite a beating. What drawbacks are there to the disposable leads vs. reusable? Also, what is the difference in using "cup" leads and flat leads?
