Haha. I saw those on HBT!
The only recommendation I can make is if you are interested in greater flow, is to purchase the 'Big C' camlocks. What you can see is that the barbs that are cast on these fittings is 1/2" OD, which makes for a much smaller port inside. The Big C ones have a full 1/2'' port all the way through so it allows a greater flow.
I bought mine before the Big C had been introduced, so I had to add them later.
I also have made a lot of adapter fittings with camlock fittings. I have an attachment for the air compressor to blow air through and dry out my counterflow chiller. I also have adapters that go from camlock to garden hose disconnects, as well as John guest fittings.
Brewhardware also has some interesting camlock fittings that I plan on getting in the near future (camlock to ball lock liquid, camlock to female flare, etc.). If you are going to get the big c camlocks, I'd recommend to get them through brewhardware, and add the extra adapters to have on hand if you think you'll find them useful.
Brewhardware also has a camlock flow sight glass that I've been eyeing for a long time too to add to the outlet of my pumps and counterflow chiller.
