I summited from the East on 6/9/18.
Coming from the West, your switchbacks looked snow free from trail crest. There may be patches of ice/snow in the shade, but I didn't go down to inspect.
Descending the chute might be your only option on those dates, it's hard to say. Since that's the case, I would definitely bring your microspikes at the very least. With those and your trekking poles, you'll still want to carefully step onto the snow, then walk out to a safe slide path where nobody is coming up, and where you won't crash into any rocks. Maneuvering to that position will be a lot easier with the microspikes.
Once you get there, sit yourself down, take them off, and glissade down! Go slowly since you don't have an ice axe to self-arrest. Dig your heels into the snow hard.
How do you dig your heels in when you hit ice and your speed goes from about 12 MPH to 30 MPH? I have seen this happen. You can neither belay nor arrest with trekking poles. People have died on this Chute utilizing trekking poles as their brake.
