I can work very easily with a swivel gooseneck or a carbon fixed gooseneck. I couldn't get on with working with a 25 inch gooseneck on very deep recessed windows and over awkward, very high bay windows (40ft+) on commercial work, happy working with a 10 inch gooseneck but 25 inch is a bloody nightmare to work with even on solar panel cleaning. For very challenging windows I use a 10 inch carbon gooseneck with a swivel glued on the end for extra flexibility to access them very awkward ones.
