String recommendations for a short-scale acoustic bass?

I really generally prefer flatwounds, so any ideas for shortscale flatwounds that would work well on an acoustic bass, or whatever rounds would work best. Appreciate any feedback

 

They seem to have a really good selection. https://bassstringsonline.3dcartsto.../images/ghs/ghs_phosphorb.jpg&maxx=300&maxy=0
I guess these would work but I'd love flatwounds. I wonder what electric flatwounds would work on an acoustic bass

 

Any short scale flatwounds? Like labellas or d'addarios? I really don't much about tension, guages, and how that might apply. I posted in the general bass section about this http://www.amazon.com/Natural-Electric-Acoustic-Guitar-Equalizer/dp/B005K1ONG6/ref=pd_cp_MI_0.
I'm sure it's cheaply made with cheap materials and would need work but it's $70 bucks and I'm gonna take the plunge.
