Here is another place to use one of the lip slur helpers I mentioned in the previous post - the half-valve flip. The first video talks about it, and in the 2nd video you can see it in action at 2:27! For me, it's helpful because my chops get a little tight by the end of this piece, and that last slur has to be gentle. (It wasn't quite where I wanted it, but in a 2nd take we did I tried it with just lip and it broke poorly.)
Here is the sheet music (solo part only) if you would like to try the part yourself.
