I have an '11 SL and '11 ET. My SL does feel looser on groomers than the ET too. The TBT takes a little getting used to since it's so catchfree and loose, but once you get used to it, it's super playful and fun! The Neversummer RC is pretty catchfree too, but I think the TBT is still better at it. I'm thinking about getting rid of my ET and getting something a little softer, such as Airobic next year.
