I've had similar issues with LUST tyres (2.35 Ignitors which I pinched after about 2 rides in the Peaks). Never had a pinch with UST 2.5 HighRollers or Swampthings, or Michelin Comp 24s / 16s (actually a lie: pinched one in chamonix about 3 years ago!).
Also looking for the perfect tough, light and grippy UST tyre: about 1000g seems about right for me.
I'm running a 2.4 Rubber Queen Tubeless on the front (I got it cheap!). Great tyre so far: fairly light for a big tyre (bigger than a 2.5 HighRoller), rolls fast and really grippy in the slop we've had recently.
Also really like Schwalbe Fat Albert Tubeless 2.35s, Similar size (maybe a bit smaller) to a 2.5HR, about 1000g, grippy and fast, but had a couple of pinch punctures on the rear (after a lot of use).
Similar tyres I've tried are:
2.4 Spesh Enduro 2bliss – foldy side knobs and pinches too easy.
Michelin Mountain Xtrem Tubeless 2.5 (grey and black tyre). Like a Comp 24 but lighter: great in the dry and rolls fast but clogs easy. Very good sidewalls.
I did have a Big Earl Wet ages ago: seem to remember it being big and sidewalls being fairly flimsy: I gave it to a mate.
