1. Bottle exclusively - no room or equipment to keg.
2. Currently, I use pump solely to move hot water to MLT and HLT. No pumped wort. I just got the pump to work flawlessly yesterday for first time. Next possible step would be to use during cooling to re-circ wort over IC coils. Wort HSA scares me though.
3. Thermo on HLT works. Came with pot off ebay. I use digital handhelds in the MLT. Pink disk of foam has a hole in it that I use to get final mash temp before mash-out infusion.
4. I usually use O2, but have found my transfer method to carboy to be so "foamy" that I wonder if I need it. See pic. That nylon bag came from fish store. It's about 2" by 8" and fits down in neck, thru which I use a sprayer tip to splash and filter at same time. S/s scrubby in boiler traps 98% of hops/trub; bag gets the rest of hop bits and causes a lot of aeration/foam.
5. Thanks. I copied many friends' best ideas.
