Most would recommend gardiners poles, it would be best to have two poles, a short 18ft for residential and then maybe a gardiner slx30 for the higher work, so perhaps look on gardiners website at the slx range, even the clx18 would be great for residential to start you off with! You wont enjoy using a larger pole for everyday work as they are heavier and longer when fully closed which can be really frustrating with everyday houses,
So my preference is two poles. One 18ft and one 30ft
