For the same weight and wall-thickness, latex is much tougher than butyl. That's why it can be made thinner and lighter. Personally I don't think there's really any benefits to latex given its higher leak-rate. I prefer to use thorn-resistant touring butyl tubes with Slime added. A single flat negates any possible benefits simply from extra time needed to fix that flat. And all extra time spent re-inflating self-leaking tubes.
What we really need is an automated pressure system related to TPMS sensors in autos. After inflating tube, attached CO2 cartridge to valve-stem and leave attached. Automated sensor bleeds air from cartridge into tyre to maintain desired pressure.
