Get yourself a nice frag of monti cap. This has to be one of the hardiest SPS. Birdsnest is also a relatively good choice, however I think people tend to overestimate its hardiness because of how freaking fast it grows when it is happy.
As for the MH/LED debate, that's probably best for another thread as it can, has, and will be debated forever.
this.. for me, about any montipora has been super easy except one green w/ blue polyp monti that refuses to turn green for me :headwalls:
I had a lot of issues with birdsnest when first going to SPS. I'd try those second..
