LPS and SPS - Bare bottom or not?

I am in the process of planning my 75g and seem to be at a crossroad. The tank will have predominately LPS with some SPS and perhaps softies in it. I like the thoughtof the bare bottom since I can have lots of flow and easy to keep detritus cleaned out. But I have heard that LPS and softies do not do well in bare bottom. My lighting is a TEK 6x54 fixture, so I don't believe I can be SPS dominant. The sump is a 30g with a LG 4-MDQX-SC return pump. I will also have a Sequence Dart for the CL. So should I go BB or not? I haven't drilled the tank yet, so I can layout the CL anyway needed if that makes any difference.

Thanks!

If the idea of going BB is so you can have very strong flow, you might have a hard time keeping a lot of the larger more spectacular LPS corals happy, as many prefer subdued currents-- Trachyphyllia, Scolymia, and Cynarina especially prefer gentle flow.

The idea of BB is not solely for more flow, but that is a big plus. Mainly it seems bare bottom is a little easier to keep clean. I plan to have fish in there as well, so I am planning on the bioload to be a little heavy. I don't mind stirring the sand and I can throttle the Dart back to reduce flow but you can't stir the sand under the rock. The CL would allow me to keep the rock clean underneath due to how my LR will be placed, but then it would also blow sand everywhere.

My plan at this time is to keep some "easier" SPS in the top half of the tank and the LPS and softies in the bottom half.
