We have a name for people who use plastic reels, of any size. They are called masochists. I have a 2509 but didn't like it. Didn't like loading it, didn't like the results.
I use metal reels for all my 120, 127, 135... I use nylon screen tubes inside a System 4 tank for 2x3, 3x4, and 4x5 sheet film and I use Unicolor drums for 5x7 and 8x10 film. Why make your life hard?
