I'm definitely interested in the results.
I am on the same quest you have been on I think. I just got a plate chiller and am so paranoid from all the stories of them getting gunked up. Two common solutions to help reduce this was to filter as much out before your PC and be vigilant with flushing it immediately after use. So far, I have purchased a bazooka screen, a hop stopper, a hop rocket, and a false bottom in trying to find the best way to keep the hops from getting to the PC. Haven't used the hop rocket yet (my hope is that it would provide great hop aroma but also filter the wort) but I know I will need something else in my keggle to catch the hope leaves prior to getting to the hop rocket. The bazooka screen may be ok for styles other than IPA's but I brew a ton of them so that won't work. I also haven't tried the hop stopper yet but it may have a similar problem as the bazooka screen but less because it has more surface area. I tried a false bottom with a pickup tube this past weekend on a iipa with 15 oz of hop leaves (12 gal boil). It was a disaster. The screen moved and the hops clogged my valve. I ended up sanitizing a trash bag which I put my arm in to thread on my bazooka screen on my valve. It was the only way I could filter my wort without using an autosiphon with something wrapped around the end.
So needless to say I'm still looking for something that will work reliability. I still need to try my hop stopper and I think my issue with the false bottom was that I didn't crank down my pickup tube tight enough. So I might try that again as well. But I am still intrigued with the option of this SS basket screen which is the topic of the thread.
