If you do use multiple 25-pair cables, and only have one reel, one way to go about it is to find out (for sure...but don't be short...better to be a little long) your total end-to-end length for the run, then pull off and cut multiple lengths. Then once all are cut to the right length, pull them all through at one time. Just a tip. I'm sure this isn't the best way, but if you only have one reel, don't want to pull it multiple times, and can figure out a good accurate length, it'll get the job done.
