Is it even worth blending with RO, or should I go 100% RO?

That is fairly mineralized and not well suited for brewing. However, it can still have utility in brewing. I suggest that for the most part, going with 100% RO and building the water back up is the way to go. Its when you need alkalinity in your mashing water that you should consider blending a bit of the tap water with the RO.

I would take that water and blend any day over my tap water...
