Tim,

Just in case you are not familiar with the Jobo processors, they are 
available with a gizmo called a "lift" that essentially allows you to 
quickly fill and empty the drums whilst they are in motion.

I was suggesting that the film should be washed (following dev and 
fix) in the (rotating) drum on the processor through a number of 
water changes, then the film should be removed from the drum and 
dunked in some photoflo rinse before drying.

Does your unicolor base have bi-directional rotation - ie does it 
reverse during processing?  The Expert drums are designed to work 
optimally for a particular speed of rotation and frequency of 
reversing.

You'll probably get the best out of the drums if you use them on a 
Jobo processor (CPA2 or CPP2) with a lift.

Cheers,
