Hip Hop Skid Bikes / Hipster Sleds / HHSB

If i am not wrong the top tube isnt the difference, its the head tub angle.

both geos here:

yep. tube length almost excactly the same just head tue angle diff. shorter WB.

I'm not particularly bothered about the paintwork, as I will most likely matte-black-murder it.

I was under the impression that the Histogram and the Bolt had different geos, which I am more worried about, however, all the sizing charts I can find are exactly the same. I need a short top-tube because I'm a combination of T-rex arms and my spine is fucked, so I'm erring towards the Histogram, geometry wise.
