Flashgals is coming out very soon. It not only a tube but also a CMS. You create tube directly from ST/TGPX/SR/RSTGP etc., or whatever script you are using so nothing new to learn and no complex integration needed. You build your tube directly from your thumb rotating software.

RASCAL TEEN TUBE
The nicest thing is it can automatically convert your existing MGP to tube with very little work.
