I got one old style and I feel that is easier to load film with it, than the new type. I use it together with a new type on a 1500 series tank for color and E6 dev. I learn to develop in one of the old style reels and tank. And I still have a old 4000 series (I think, that's the number) with 3 reels, but they are larger. Use it for when developing 3 120 films.
