I've tried the 3 readily available sets and have made some of my own.I needed smaller than 1/4" and couldn't find any so Mike Krantz told me to try a knitting needle cut in half. I did that then drilled out the inside and tapped it so you actually screw it on to the line. Works great. Another good trick is the get some small wire and double it, push it through backwards then pull you line through with it.
The very best (also the most expensive) is the Brion Toss rigging wand. I got the micro. I probably don't use it enough to warrant the cost but it works like a champ and saves alot of headaches.
