One more day. I cant comment on the changes yet but i can explain the Rally/RPM differences.
The RPM is very versatile bit it is freestyle oriented. It flies further back in the window to deliver more unhooked pop and more power through the kiteloop.
The Rally is called a surf kite, but I tend to refer to it as the all around kite. It flies closer to the edge of the window so it upwinds better, has incredible drift and better low end. It unhooks rather well, but not as much pop as the RPM. Kiteloops are adequate but nothing compared to the RPM or Fuel.
Ranging from Freestyle performance towards all around user comfort i would range them like this: Fuel -> RPM -> Rally
Ahhh so the rally is more towards surf/alround riding. I used to have a RPM and I loved it! It was so easy to fly and it was really good unhooked although it doesn't have a lot of slack line after you pop. Which is why I switched to the hadlows.
Also can't wait to get the new ss asylum!!!!
