SS in Whistler
Great Handle NamaSSte!
I live in Whistler, and ride my SS about 65% of the time.
Lots of great trails for you. I ride a 32x16.
The Bike park isn't the place to ride a SS, but here are a few combinations of trails you could put together for a ride. It all depends on how much you want to ride, where you're staying, etc.
South of Whistler Creekside (south little village) there are the Riverside trials which are pretty buff (really dusty right now) and not technical. If you want something a bit more technical, you can ride Trash, and Train Wreck (where there is an old train wrecked through the middle of the trail, very cool).
From Whistler Village you can combine Blueberry (which is really more of a connector trail, but good fun), with Cut Your Bars or River (as already mentioned).
Also, from the Village it is really easy to check out the trails in the Lost Lake area. It's where we have our XC ski trails are in the winter, so there are a bunch of single track trails intermixed between lots of gravel road trials (closed to cars, just bikes and hikers).
I would highly recommend Thrill Me, Kill Me which is a bit north of Whistler (not drive far, about a 20 minute ride to the trail head). It's one of the more popular trails in Whistler (along with River). You can combine Thrill Me, Kill Me with Section 102 if you wanted a bigger ride.
So, as you can see, there are lots of fine trails to ride SS in Whistler. No need to go to gears.
