Replying to Help getting grips off Goode poles

Ok I know how you are normally supposed to take off pole grips by heating them up and pulling, i have done it before, but this is different. On goode poles (im not sure of the model name but they are a brown and white fade color and the grips are white and black) There is a bolt you can loosen at the bottom of the grip and i did this, heated them up and pulled to no avail. I can not get these things off, i checked their website and apparently this grip can be rotated to make the pole shorter. Has anyone had any success getting these off or at least rotating them to make them shorter? Thanks in advance.
