What are best 220 developing reels?

[Dick Sanders]

Anybody here with 220 experience who can recommend the best developing reels? And where to get them? I've long developed 120 bw film on stainless reels, but I've been wanting to shoot 220 in my Pentax 67, in order to get more shots on a roll, and to cut down developing time. My reels only take 120 film. Thanks.

I've devved 220 on the nylon 35mm reels, its simply a case of twisting the reel to unhinge the bayonet then extend to fit 120/220 roll. H
