I actually like the past intermediate speed trick round, the pressure makes alot of people crack and is always a good watch! I would like to see a stalled trick in there though. I know it's a speed trick round but even the beginners have a lighthouse.
I think if you tweaked it a little towards the end it would be good so something along the lines of:
1. Knee Bounce
2. Around The World
3. Aeroplane (From Held start)
4. Jumping Stick (From Previous Aeroplane, if missed trick 3 must be done again too)
5. Earth Turn (including Swing In start)
6. Trapeze Acrobats (Minimum 2 rotations)
7. Moshi Kame x 10
8. Lighthouse (held 3 seconds)>falling in
That makes 2 what I like to call "struggle" points with both the jumping stick and lighthouse in play, its a small change but feel would add the the tension

As for Advanced, I always like the mix of solid and quirky tricks. I think a few more Dan tricks would be nice, especially on the higher end of the scale, mainly 2 turn lighthouse haha, id love to see that there. Oh and everyone can earthturn whirlwind these days, just throw one in for good measure haha!
With such a diverse group of players i can see how it is hard to accommodate tricks to try and challenge everyone. Cant throw too many string tricks in the mix as someone might be hot stuff in that area and same goes for balance/stall tricks.
I do like the call for longer tricks though, so more simple tricks but put in a lcombo to make it harder. Lets say for example: lighthouse>big cup>bird>in. On their own not too bad but having to put them together makes it harder overall.
I dont envy the job of having to decide all these so hats off to you!
