Thanks for the reply's!
I asked the company I ordered the short ends from to spool them over in 200" lengths, and I checked today to confirm that the film is indeed delivered on 200 daylight spools.
I am looking for a 400" magazine on various outlets, but they seem to be very hard to get by, with prices pretty steep from film company's :-)
The real question is, has anyone tried using 200" daylight spools with the ACL magazine? Will it rub against the inside of my magazine and make excessive noise like with the NPR as John mentioned?
