Yah that primeline is good stuff, made by Lindgren-pitman, Corey put me onto it. It's the stuff that commercial swordies use and it's strong. Phil's rigging a ton of guns that he makes, a 5lb coil will last you a while. I also order stuff from here, and I think this might be where I ordered my crimps: https://catchalltackle.com/crimps/
Make sure you are mushrooming the end of the mono (with a lighter) away from the rest of the line ie. you pull the line thru the coil a ways up and then mushroom it, let it cool and then back down the sleeve till it's a little above the mushroom. You don't want any heat near the main line and you want to change that line anytime you get a nick. I had a thread on the old forum about crimping mono that I got out of a fishing mag, I'll see if I can find it and resurrect it.
btw the left over shooting line works great for weed wackers if you are doing your own yardwork. I also keep a short piece on the boat to unplug the peehole on my outboards and you can make stringers out of them too.
