What Midtops to use in dance stack?

So I have been wanting to build my own dance stack for a while but I'm a total beginner at DIY speaker building. I have been talking to some friends who have done it and what they reccomended and what I am thinking about so far is to build 8x Cubo 18 Extended, 4x HD15 kick bins, and a couple of mid/tops but I am not sure which ones would work best. Can anyone give me any recommendations as to which mid/tops would work best with this plan?

Thanks!

I used to use a very similar set up with mt121 mid tops...

setup was
8 cubo pd1850 loaded
4 fane 15" mid highs these were doubles
4 mt121's 2 per side.
