I dont really know what to make of it , it tells me that it will be more rigid held out in front of you but side to side flex by laws of physics should be more , fine if you are straight on to the window , but if on a long stretch over a connie it might well put you worse off , the wear will still be in the same places as a round pole , and as a consequence the pole will have up and down movement over time , which will wear the flat sides possibly more ?
