Jobo has 2 styles of drums, the standard reel types and the "expert" drums.
I am using the expert drums on a daily basis for 4x5 and the processing
is *perfect*.
IMHO the expert drums are well worth the cost especially if you cherish
even toned skies!
The Jobo reel type of drums are notorious for "less than" even development.
Even the newer style with the extra flanges.
By the way my reel type drum is for sale. Any takers? :)
