Yuge!
I used 1 gallon paint strainer bags and each round got its own bag. For classic IPAs (which I guess would be low-throw-weight WCIPAs these days) there'd be an ounce or two at 60 floating around, then a couple more at 20, a couple more at 10, and a couple more at FO. So now there'd be four bags of hops roaming around in the kettle, and I'd be compulsively picking them up with a set of SS tongs to drain them then dunk them back in the wort. Really obsessive stuff, but I was convinced if I didn't manipulate the bags the utilization would be pathetic.
Also, if one has never used nylon hop bags, here's a heads up: nylon mesh tightens over time in the boil. You might notice after say a dozen uses that you can pick a soaking wet bag of hops out of the boil and realize it literally isn't draining! No bueno - clearly utilization goes down the tubes at that point.
All of this stuff is what drove my hunt for a rational, functional, effective, and non-aggravating solution. I surely don't want to look like a shill - I don't think I've even mentioned the company's name - but this solution is the best I've tried yet...
Cheers!
