hey, just my 2cents on your specific build. you've invested in Momentum as well as Shield Barrier, which is good, since your end game gear sets give you a bonus to your Shield Barrier.
Barring one or two skill points, i have same same build, and usually go with,
Saber Throw +3
Force Leap +3 (6)
Blade Storm 0 (6)
Sunder Strike +3 (9) - this one is important to start building your Sunder Armour
Riposte (use on cd, especially since u have it talented) -1 (8)
Guardian Slash -4 (4)
And with that one rotation, you should be able to start again, and you will have your target on 5 sunder buffs already, meaning anything you hit him with from now will be pretty solid.
If it's a group of mobs, I usually throw in a Force Sweep after the Blade Storm, but I have Courage talented, so it is a little cheaper.
Also, i find that even as a lvl50, within ops i still tend to use Force Sweep for the 5% accuracy debuff on some of the bosses.
I am not sure if you're PVP or PVE, but as a suggestion (from a PVE), I would take out Force Clap (since it won't stun bosses) and probably Force Resolution (since I find that Enure is just a buffer for the Healer to get back on his feet and start healing you again - it's not intended as sustained health imo). I would even consider removing either some points or all from Inner Peace. These extra points could be better used on Courage and Dust Storm. I found Dust Storm works even on HM and Ops bosses, so is still worth while, and since you have invested in Blade Barrier, Courage will help with the cost of Force Sweep as well as Blade Storm, which I guess you like to use, since you have invested in Blade Barrier and Momentum.

This is still a little different from what I am using, but I'm trying to align it to what I think you might be going for, with as few changes as possible.
NOTE: I don't mean to be sounding like I know any better than other people, and I certainly don't mean to be sounding like I'm telling you what to. This is all just from my experience and my style of playing.
