I tried it out, not sure why locking in the claw enchant won't stick -- I'll look into that.
If you're using one of our default gearing strategies, could be that under some circumstances claw is not quite as good as hidden satyr. I would recommend creating a custom strategy for your character.
That said, I simulated the enchants for your character as you posted above: http://www.askmrrobot.com/wow/simulator/report/da7b8c2e2c8343cd9275757ef0e40c5f
Claw came out ahead, but they are pretty close. That is actually within margin of error of the simulation that I ran, I would need to lower it to determine which is actually better. So looks like you could go either way on the enchant and barely tell the difference.The default strategy says claw is only 1000 DPS lower than satyr -- that is a very small difference, well within any reasonable margin of error for a simulation.
As for legendaries, I would highly recommend making a new custom gearing strategy -- things can change quite a bit depending on your talents, legendaries, set bonuses, etc. We're working on some big updates so that our defaults are more adaptable with ToS, and so that you won't need to create your own custom strategies as often. But for now it's the best way to get advice tailored specifically to you.
I would suggest equipping the legendaries you prefer, then follow this guide to make a strategy around it: http://forums.askmrrobot.com/t/stat-weights-how-to-generate-a-custom-gearing-strategy/57
