Sounds like it could be a pressure thing. I ran NN/RR combo for about 6 months (tubeless). Light and fast for sure but fragile. I would find the sealant seeping out of little spots on the tyres so wonder how many punctures I would have had to deal with.
I ran my front NN at rather low pressures but never had a pinch…saying that I was very aware on the rocky stuff, fully expected to get one but never happened. Maybe that is a tubeless thing? I don’t know.
Tubeless all the way buddy, might be a pain to set up initially but not stopped for a puncture in at least 2 years. And that is worth it to me!
Now ditched the Schwalbe combo for Maxxis…but that was a grip related issue!
