Flurry of Blows / Two Weapon Rend / Double Slice

[Driver_325yards]

Does Two Weapon Rend and/or Double Slice work with Flurry of Blows?

Note: I am no asking whether TWF works with Flurry of Blows.

Also, does its make a difference if we are talking about regular FoB or Unchained Monk FoB?

Double Slice wouldn't work. Monks already add their full strength bonus to Flurry. Double Slice is missing text of "instead of 0.5x strength".

Two Weapon Rend seems to work, but that is a lot of wasted feats for 1d10 + 1.5x Str once per round.

Double Slice would do nothing since flurry specifically states damage becomes x1

I'd say TWR would work only if the monk is actually flurrying with weapons. When fighting unarmed, monks do not have offhand attacks:

Since you must land an offhand attack to be eligible for TWR, would have to use actual weapons to achieve that.
