we had the same problem and a year down the line we still have the somw problems, obviously no where near as bad... in our job you realise that we are a nation of moaners and complainers and no matter how hard you try you can not please some people. Im glad to say though that now things are very settled with the pole and people have generally come to accept that this is the way it it.. we just do upstairs with the pole and make it more of a safety factor and also we generally get good results all the time without doing the top frame, we tell them if they want frames doing its extra and expect a few spots on the glass and people are more than happy with that..
stick with it because we would never look back
