I have a Sun C4 with 38 slots. I have two backups; archive and daily.

For the daily run I use slot slots 1 & 20 and for the archive 30-36. I
have my cleaning tape in 37. When I got the C4 I switched to the
chg-zd-mtx script. I find it works great. 

The only parameters I have set are for the archive and daily and the
only difference is the firstslot and slotslot vaules.

Firstslot
Lastslot
Havereader
Offline_before_unload. 

Everything else I use the defaults.

Most new changers seem to take care of cleaning based on the amount of
usage of the drive so I do not do anything with cleaning it just works.
