Oh btw, don't try to roll Fuji onto a Kodak spool. The Kodak is not wide enough and it crimps the Fuji paper. Ilfords reel is in-between. The "inside" spec's by digital caliper is Kodak: 63.01mm; Ilford: 63.04mm; Fuji 63.22mm. (your mileage may vary). I'm sure spools vary, but I'd only use the take up spool of the brand I'm shooting.
