Shatter vs. Sands of Mu

Hi All,
Picked up Shatter yesterday on my SD/WM and was reading through the "real numbers". It looks like Sands of Mu is more efficient (DPE) and more damaging on average and per activation than Shatter. Granted, I haven't slotted the thing up (6 Multistrikes) and Sands is not affected by damage buff powers, but this made me wonder whether or not I should just stick with Sands and dump Shatter or if I can rely on Shatter in the long run.

What do you all think? What's your experience been?

If you want to be certain that you're comparing apples to apples, there are a few things to think about:

Are you comparing Sands with Shatter enhanced for damage or unenhanced?

Also, since Sands cannot be enhanced for Accuracy, you'd need some global accuracy bonuses to match Shatter's accuracy, since presumably you would enhance it for accuracy.

Have you taken into account the animation time of Sands vs. Shatter? I couldn't find the animation time of Sands online, but it certainly seems like a much longer attack than Shatter.

Lastly, keep in mind that Shatter has 100% chance to KD, and Sands doesn't offer any similar secondary effects.

I haven't crunched the numbers, but my gut feeling is that Shatter is a better attack when everything is taken into account. Sands' damage type is less resisted, which is a point in its favor, but I wouldn't make it a routine part of a my attack chain, mostly because of its accuracy and animation time.
