Re: EXO + vs Double Down for rear tire

Related: DD vs EXO & CushCore rear, opinions/experiences?

I've been on DD equivalent rears on my Patrol for a while (Michelins currently) but ended up needing to run 28-29psi recently to avoid flats from rim dings. Put a CushCore in there for the last few rides before the snow arrived and dropping to 24-25psi felt great. Wondering if I could get away with an EXO with CushCore to save a bit of weight. Sidewall durability isn't really a concern - only ever slashed one and that was a very lightweight Schwalbe. Guess I'll only know if I try it. Or just run what I have now and not worry about it? 80kg rider in a very rough part of the Alps and take a BC trip each autumn.
