Mine doesn't appear to have the problem of nosing over. You might check the thrust line of your engine. The ultimate should have a slightly right and upwards thrust line. If it doesn't it should. Also, make sure that the engine is mounted nice and strong so that it doesn't have the ability to move when the throttle is applied. The ultimate should be a rock solid hover'er (if thats really a word ). One of my favorite things to do with this bird is to hover it a little high and then tail slide it backwards and do a rudder touch and then rocket it skyward while rolling. It will stay nose up in a hover while falling backwards slowly. I would try a new prop and check your thrust line but don't make any drastic changes until you try the new prop. I think that the 12x6 prop not only makes it torque roll hard but it may also be the reason it is pushing forward in a hover.
