I'm very pro rope tow - but! I seriously think Granite is just as fast - granted i've only been there 2 days in my life.
1. its a high speed 6 person - if theres a liftie making sure chairs are full -theres really not much of a line.
2. you get to go along or over the park the whole way up (so you can watch the homies)
3. the run is top to bottom park - one beef I have with out west is if you take a chair - only 1/3-1/4 of the hill is actually park. You can hit so much stuff top to bottom. No choosing jumps or rails - you can hit it all on the way down!
I seriously filmed over half my season edit in 2 days when I went there a couple years ago - very productive all in smooth long laps
