Michelin does make really wide latex tubes that can be cut down for wide 584 tires, other than that, I am with you. Not a fan
My preference is either Silca or Vittoria but Challenge does make a wide one for tires up to 38 mm, so, I use them too. Sealant works reasonably well inside latex tubes but eventually you are wasting a tube because the sealant dries and buggers it all up.
Today I pumped my tires up to 95 pi, 5 psi over optimum and they will be 85 psi tomorrow. About 10 psi loss per day for those two. In effect, I pump them up every other day. If I was doing some sort of timed event, I would be more concerned but it takes me under a minute to top them off. Even if I run butyl, tire check is something I do on every ride.
