The slack was the problem of my one and only so far pull/pull system. I believe and hopefully someone will correct me if I'm wrong, you get it as close as possible and tighten it up with the adjustment screw.

I use eyebolts and clevises for pull-pull. If I'm using Kevlar, I run the 'cable' through a sleeve, through the eyebolt twice, and back through the sleeve. In most cases there is enough slight resistance that I can pull out the slack and it will stay out while I crimp the sleeve. If not, I give the sleeve a little squeeze with ordinary pliers, pull the slack out, and then use the crimping tool. And yes, you get the final line tension with the threaded eyebolt. At least, that's the way I do it.
