If you use pellet hops, that kettle tube screen will clog like crazy. If you use leaf hops that kettle screen will get them all, and filter out the hot break too, since the leaf hops set up on the screen, and then the hot break can't get through. But trust me, do NOT use that screen with unbagged pellet hops. Ask me how I know!
Paint strainer bags are awesome. I build a "hops spider" with it, I use one to filter things, hold hops, etc. An easy way to use one if you're using buckets is to sanitize a large (5 gallon size) strainer, and line the fermenter with it. Dump your wort in, pull up the paint strainer, and you're done.
