I studied with John Swallow, who was a huge champion of natural slurs and natural breaks (and alternate positions).
I'd love to see what's possible if John Swallow's teaching were applied rigorously to bass trombone.
Oh hyperbolica, I could spam you with so many question on his playing and teaching, but you don’t want that because I’d counter every answer with more questions.

I never met him but the recordings I heard from him are incredible. I am sure you know this but for me this was very cool of a resource to have.

Back to topic. I am not necessarily speaking about Legato. What I hoped to describe in my post is when I hear a player who is very obviously having good slide technique control...until he reaches a technically tricky low phrase that forces him or her to move the slide while having to apply a mix of open, one valve, other valve, absorb valves. What I sometimes hear then is that the musical line starts to suffer from the players focus on technically clean execution. I believe this may in some cases have something to do with how the triggers are applied.
Specifically, I wonder if THE WAY the trigger/s is/are being pushed/released may influence the sound and flow of the phrase.
I am not speaking about timing, good timing is a given.
For instance: A jerky, tensed slide movement, will have negative effect on a phrase, even if the slide arrives on the next note in time. It can be very audible to the listener.
I wonder if a jerky trigger movement in the low range can have a similar negative effect and if anyone has thoughts on that being a possible cause of problems for young bass trombonists and if this is addressed in any literature.
