You seem to have two LLS enduro bikes, so swapping one to a mid-travel 29er bike would be optimal IMO.
Would a slack/long shorter travel bike still be what I’m talking about? I wish I had bought the meta tr to be honest but I didn’t think about it!
The Meta TR and some of the other bikes you mentioned are on the hefty side, I’d look for something more in the average weight zone. The new Vitus Escarpe and Sonder Evol both look good. The Norco mentioned above, the Stumpy Evo, the Hightower you suggested yourself.
I have a big heavy enduro bike and a lighter trail/enduro bike (Stage 6), and it makes a really nice contrast for me.
