When affixing augments on Jet Boots; what augments should I be looking for?

Depends; are you using Switch Strike?

If you are, you want anything that adds MEL-Pwr.

If you are not, you want anything that adds TEC-Pwr.

is what I'm using currently. It's not completely optimal but I didn't have to buy any affixes as I had everything in storage. If anything I would like to replace Mutation with Flict or Sentence Magia, though Phrase Weak is very interesting as well.

This is my current setup. Not maxed out but I was able to put it together with weapons I had hoarded. The only thing I had to buy was the tech/pp affix. Ideally I would like to replace Mutation with Flict or Sentence Magia or Phrase Weak.
