Using RO water as a starting point for recipe water instead of distilled?

minimum dose size?

I use the Hario switch to brew my coffee and am trying to reduce my caffeine consumption. Hence I would like to brew smaller cups of coffee. I am currently using 10g of coffee with 160g of water. (1:16 Ratio) I am wondering if there is a minimum amount of coffee...

Using RO water as a starting point for recipe water instead of distilled?

I'm curious as to what the consensus of using RO water as a starting point for recipe water is. I know solutions like Third Wave Water are intended to be used with distilled water as a starting point, but I have reasons outside of coffee that I want an RO system, and indeed one is being installed next week. I also know that using pure RO water isn't ideal either.

My area has abnormally high TDS of about 1200mg/l, and a Ph of 8.5. Now, I know TDS by itself isn't really a great measurement since I don't know what solids are actually dissolved. Just by looking at the bottom of my tea kettle clearly water hardiness is much of that, but it's also because I don't know what's really in there that I'd rather just start with a blank slate. I live in an agriculture heavy area and it could totally be nitrates and lead and other things, so I'd rather just get rid of it all and add it the stuff I want back in.

Because of this, buying distilled/filtered water for basically all my coffee/drinking/cooking needs quickly becomes very expensive, hence the RO system.

Now my question is since I'm not starting with distilled water, and there will probably be some TDS left over, does anyone have any experience in making water for coffee starting with RO water rather than distilled? Can I just throw in a packet of TWW in RO water like I would distilled?
