I gave high RTT with high bandwidth a try:
server   --   delay  --  mbox  --  client
netserver   300/300ms  45/900mbit  flent

I had to run flent with "-s 0.61" in order to avoid errors with fping dying prematurely.
Comparing noack, ack, and ack-aggressive, ack seems to give the highest download rates.
Cake was setup with "rtt 600ms".

High RTT with relatively high bandwidth is traditionally considered challenging, and is representative of Australasian and satellite connections.  Definitely do some of those.

Low bandwidth should also be interesting.  DSL at 4/1 Mbit is typical entry level package here.
