I found developing 220 film with a Paterson reel inconvenient. The Ilford 220 b&w film felt even thinner than the Kodak stock. The nicest way to do regular tank and reel developing of 220 is with a Nikor wide spaced 220 tank and reel set. They are available on eBay and like most accessories for 220 film sell for much lower prices now. Very few people are interested in 220 backs or inserts at any price.
