I think the Torrent brush in the Amazon link could be useful if you have curved areas. I have some curved walls and corners in the deep end and it's really hard to get into some of those areas and maintain contact with a flat brush like the Ace Hardware one you show. I've always been curious about one with a fin, like the Whale Wall or SweepEase. That might be enough to keep the bristles in contact with the sloped corners. I think it's really hard to tell which brushes lose bristles and which don't. The standard brush I have now is like the one in the Ace link and it's been great for the past three years, but others have shedded bristles all over after a few months. It seems like the Whale Wall and SweepEase are better quality, so they're less of a gamble when it comes to shedding.
