Fully agree with the 3 largest brass offsets - they have been my bomber placements when nothing else would work, many times. Just make sure you tell your second how to clean them (hard yanking wrecks them quickly, precise nut-keying is best). I have placed them a few times on grit too, but not as often as on other rock types.
For connecting to anchors, a Dmm Boa is highly recommended, or a Petzl William (I think those are the equivalent ones) - they are bigger than standard HMS and more friendly for this purpose.
Some people might not agree, but I find a mixture of nylon and dyneema slings is good. The 8mm dyneema ones are great for rigging and threading tiny holes, and I often prefer the 16mm nylon ones for slinging flakes - as they feel like they won't "roll over the top" as much. Also the nylon ones are a bit better for cowstails, as they don't snap as easily as dyneema when shock-loaded.
