I don’t totally follow you, as I never experimented much. In my experience though, the LST 2-Speed is absolutely rock solid reliable - as long as you don’t change tire size etc too much.
Vastly better than Savage trannies for ex. My trannies lasted years - til I put in the LRP ZR.30X anyway. They don’t seem to like excessive power either I guess. But with stock size tires and say an LRP 28, in my experience the trannies last forever... And the shift point doesn’t wander (like on Savages..) They are sensitive to experimentation in tire size and to bigger engine power I think..
