I have been using the ultra lights with the tan sidewall. The sidewalls are translucent. Very, very light tires with a delicious ride. Supple. Sort of like riding on just an inner tube as the tire.
When I first installed them, the front end washed out on clean dry pavement and I wrecked. I blame the mold release on the tires combined with the pressure at 40 psi. After the crash, I took a long ride in the dirt to scrub the mold release off and now run the tires at 30 psi, which seems ideal. I have been a little reluctant to corner real hard (still have the road rash) but I'll head to a parking lot one of these days and see how far I can lean them. I rack the wreck up to operator error.....(I knew about mold release on tires).
Compass tires are designed to offer optimum performance above all. Their supple casing is key to making these tires roll faster than most. It also absorbs vibrations and shocks better, making these tires supremely comfortable. The tire tread was designed to offer optimum cornering adhesion and precision, both in wet and dry conditions.
Despite this focus on performance, Compass tires are sensible everyday tires. The tread is 3 mm thick in the center to last many miles, unlike thinner high-performance tires which are best treated as “event” tires. We at Compass ride our tires year-round on the road, on gravel and in the city, without any problems and with very, very few flats.
I sold the standards to "upgrade" to ELs. So far don't think EL's are worth the price. Was just in G&G and got standards to put on once I wear through the ELs. Same amount of tread, walls are thinner, more difficult to seat the bead tubeless. Tread life is less of a worry than sidewall damage.
If you are value-oriented or prioritize grip, there are some better tires, but if you wanna go fast these are the way to go.

Love the last paragraph of the Riv quote.

Listen to what Keith Bontrager says about wide tires. Not directed at you Jan. It is at 2:35.

The Rat Trap Pass use the same casings, same tread pattern, and same tread thickness as the other tires in the Compass line. We did a lot of testing with prototypes to make sure that you could actually use such a supple casing on such a wide tire – nobody had ever done that before.As to tread wear, the wider the tire, the more rubber touches the road. So the wear is spread over a larger surface, and the tire lasts longer. It's that simple. Our tires have a somewhat thicker tread than event tires like the Soma Grand Randonneur or the Pari-Motos. Again, we did a lot of testing to see how thick we could make the tread rubber without slowing down the tire significantly, so we could optimize speed and longevity.I get about 5000 miles out of a set of Babyshoe Pass tires before I retire them. When I cut them apart to check the wear, I am always surprised how much tread is left – I probably could have ridden them another 1-2000 miles. I haven't yet worn out a set of Rat Trap Pass, so I cannot comment on how much longer they last.Of course, you'll find tires that last longer (harder rubber that doesn't grip well, thicker tread that rolls slowly), but for a high-performance tire, I am very happy with the mileages we and others get on these tires.Jan HeineCompass Cycleswww.compasscycle.com

Those Stampede Pass ELs on West Mountain, Hot Springs, National Park, AR

I've switched to running a 2.1 racing Ralph on the front and a RTP on the rear. I've found it a nice setup as long as I'm extra careful to steer clear of sharps.
I'll continue to run them on the rear. I think they're good all around and easy enough to patch. I think they're worth the comfort and speed. IMO. Hopping on my bike with schwalbe marathons just feels harsh and dead to me after such a cush ride.
