I leave the tails of my leaders out when I unload my film (and fold them over so I know whats shot) - It lets me thread the first inch of the spool in the daylight before I load it all into the dark bag. No more fumbling in the dark trying to spool up. A simple snip at the end of the roll and I'm done.

I also made a little 1/2 -inch PVC frame for my bag to create a poor man's tent and give me some working room.
