I use what ever brand I can find in the 5,15 and 30 min. Loctite and Devcon are the most common.
I use it to glue popper bodies to hooks, and to coat heads/eyes on patterns as needed.
I've only ever used the double syringe type and have found that you just have to be VERY careful when pushing the plunger. you can vary the amount on either side by pushing more on one side or the other on the plunger as needed.
Also after you squeeze out what you need, pull the plunger BACK OUT a bit and it will relieve the pressure inside the syringe and keep it from leaking before you can put the cap on it. Just like using a caulking gun.
For 5 min, I keep a pad of 3x3 post-it notes and a jar of tooth picks on my tying desk. If you need to mix up more than will fit on the post-it note, you probably need longer than 5 min epoxy.
Oh, and keep a bottle of regular nail-polish remover (acetone) on hand when working with epoxy for easy clean up.
