Always glad when someone speaks out for the backlock...
A bit ot, but your post is just such a good example for what I believe most real knife users would say when carrying (and using!) a backlock knife for a longer period of time.
To come back to the topic of the thread again: I already stated that I generally rotate (just) between Endura 4, Stretch 1 and now Endela SE.
But I almost never "rotate" between locks, it's almost always a backlock.
And always a quite light knife.
And always a steel not too hard to sharpen.
