Wanted: more aggressive filtering options

I'd like to see more aggressive filtering options, beyond "best," particularly for very high volume feeds.

For example, TreeHugger generates 560 posts a month. The "best" mode shows the top 14%, which still works out to 78 (!) posts a month:

That's still way too much. I'm interested in TreeHugger, but I can't commit to reading more than say 10 or 20 posts a month (the top 2-4%).

Without a super-aggressive filtering option, there's still a large number of high-volume feeds I'm unable to read.

Thanks for your help.
