i would say yigal mieska, i have never tried it before but it works for pros so yeah, but what ever you do don't get pet 2.0 it sucks the million dollar knot is great but the tread suck a**
Yigal Mesika's Loops are great, yes. Definately buy these if you are new to IT work and would like to learn the theories and mechanics.
For the record, PET 2.0 is a fantasic IT if you know what you are doing. It's SUPER thin and can break easier than LOOPS but they are INVISIBLE in all senses. I have never been caught with a PET LOOP. Mesika's thread is another story.
Caveat Emptor: BE VERY CAREFUL WITH ANY AND ALL I.T.! They will break at a blink of an eye if handled incorrectly.
My preference though is Yigal's thread only because of the reliability. The best thread for worker's. But, PET 2.0 is the most INVISIBLE but is weak in strength.
(For the record, I can't say anything about Infinity Thread only because I have not used it. I someone else would churp in on that, the information would be appreciated.)
