The thing about brushes for me is how much different each style works. I haven't used every brush out there, but I have a few favorites at the moment.
Latex Brushes/All 3"
I reach for the Purdy Nylox "Moose" and "Bow" for residential walls/ceilings when I need thick coverage. The XL series "Bow" is great for cutting flat paint in same color schemes like apartment re-paints. It doesn't hold as much paint, making it lighter and quicker for me.
The Wooster line of brushes continues to impress me. The Ultra/Pro firm "Mink" is also great for interior flat when I need it to hold more paint than the Purdy XL. It's a good ext. brush also. Probably the most versatile brush in my lineup.
Wooster U/P firm and extra firm "Sable" more than do there job when speed is needed more than coverage (especially with glossy paints), or doing ext. trim. They just hold there shape because of the firm bristles.
My new go to trim brush may very well be the Silver Tip flat sash/long handle. I just picked one up, looking for something softer but able to hold its shape. It was a short test, but it held some paint, applied it smooth and cut in some baseboard lip, holding it's shape pretty good. We'll see when I give it another go Monday in trim paint all day.:yes:
