I'm considering upgrading from my 10 gallon Polar Ware kettle to something with a ball valve. I'm considering the following kettle. I like the company, the kettle is made here, and it's priced well. http://spikebrewing.com/collections/10-gallon-stainless-kettles/products/10-gallon-brew-kettle-1-coupler
Of course, there is Blichman, but I don't see any difference and the price is much higher. I've also talked myself out of needed a sight glass and thermometer bc I use a Thermapen. My primary reason for doing this is bc my kettle now is as thin as a razor and I like the idea of being able to transfer out with a ball valve over pouring into a funnel.
Lastly, any concerns over using Teflon tape? The Spike kettles require it.
