Fair enough, tubeless seems to work for some, not for others. Personally I find I'm not that hard on tyres, though the wheels themselves take a beating. So tubeless works out OK for me.
So to the OP – I guess the answer is "it depends". Try some out and see how you go. I'd still recommend the maxxis freeride ones as a good middle ground if you think you need heavier than XC tubes but don't want to go for proper heavy tubes. But then it does depend where you ride*
Oh and air pressure too. I'd (personally) not go as low as 15psi whatever, they'd just fall off, except maybe in bad mud where I wasn't on a spike for some reason. Kinda weight dependant too tho (I'm 80kg).
*i've been known to run thick maxxis/hutchinson DH tubes in dual ply before for alpine rockfests.
