Not used that particular film ( and I do fancy trying E6 process some time ), but I can attest that Rollei is rolly.
I've never known a film that curls up quite so fiercely. Hang it up to dry with a weighted clamp at the bottom, and then as soon as you remove the clamp... SPROING!!!
Retro 80S, IR400, and their C41 colour film, all roll up tightly as soon as you take the weight off.
Felt like i needed three hands to get it in the scanner tray, two to hold it down and one to close the tray!
