Well Eye and Skeer's are currently BiS so I guess keeping your current setup is probably most optimal.
Eye and Thok's are BiS last time I checked for Fury. As per your choices, I would personally run the Thok 2/2 and Eye 2/2 if possible because of the gain you get from the reduction and the bonuses from Thok's trinket. If you want, you can test around with Skeer's over the flex Thok, but I personally don't like it (which is why I would run heroic feather still if I had one of those flex trinkets).
Off topic though:
If you're playing fury, why are you gemming strength? You would be gaining much more dps going into crit based gems over those pure strength gems at your currently ilvl.
You also shouldn't run that Recklessness glyph at all because it is purely awful still.

Flex Eye and Thok are both very slightly better than H TF Feathers. If your feathers are only H, then its an easy answer.
As for Skeers normal, it is slightly above, but extremely close to both Flex Eye and Flex Thok for single target only. When I say extremely I mean like <1% difference. As soon as you get into any multi target situation, Skeers drops just below both Eye and Thok.
Eye is actually the weakest of the three for single target, however with the amount of AoE there is in the tier, even as fury, Eye starts taking the lead. Plus I like it because it makes the single target rotation infinitely easier/less RNG dependent and that alone will make your damage go up. Not to mention shorter defensive CD's.
