I voted on as the option for partial removal isn't there
I've started using an immersion chiller and recirculating the wort through the hop bed (and hop stopper). In theory a lot of hot and cold break will be filtered out this way. It was very effective with my 911 IPA, but I had a couple of issues with my Quaffale, and that looked as though a significant amount of break made its way through.
When I get the conical(s) then I'm probably going to do the same as SF and dump the trub before pitching the yeast.
Fermenting on the cold break is supposed to be beneficial
IF your wort is low in Free Amino Nitrogen and / or you are under aerating. The yeast can utilise the trub as a source of nitrogen and also for sterols for membrane formation. There can be an issue with a soapy taste (associated with sterols) from fermenting on the cold break, but I suspect that it will only be obvious in delicate very pale lagers (Butwiper type beers). Given the option I would certainly want to remove the break. I can always add yeast nutrient when required, and I oxygenate more than adequately anyway, however, in the several hundreds of gallons I have fermented at home, and the thousands of barrels we fermented at work its not something we were to fussed about worrying with.
