Original Vectra Line Super Strong Invisible Thread
Vectra is the best IT you can find out there, it's extremely strong and easy to strip when you get used to it. The only downside is that is a little bright when under direct light, but that can be avoided with the proper precautions. From my personal opinion, once you try vectra you never go back to kevlar or any other kind of IT.
