FTR, if Stars was coming up with a hybrid Hyper/Turbo, my vote would be for something that adopts the hyper blinds structure, keeps the Turbo 5 minute levels, starts at ~30/60/6 with 1,500 stacks, and cuts the rake by ~25% to compensate for the shorter average run time.
Also, for people talking about how much the 10/20 and 15/30 levels make a difference for good players, go into your HEM/PT and look at what your long-term bb/100 is, how many hands/level you get in on average, and what % ROI that roughly translates to (i.e. your average +cev/starting stack).
If you gain ~2% effective (or whatever it is) from a rake cut, and another x% from shorter run time, it takes a pretty good edge at 10/20 and 15/30 to outdo that. At the lower buyins and for some really good people as you move up in stakes that's doable, but for many grinders it's not. Plus given that Net depositors have asked Stars for shortened SNG structures, and given Stars has expressed interest, I'm surprised more people aren't pushing for another shortened + less rake structure.
*Kicks dead horse again*
. Or maybe Stars uses their (possible) purchase of FT to do some future experimentation over there.
