Someone pmed me for more info about climbing the trio, and I thought my reply might be useful for others too:
I went with an ice axe, running shoes, and crampons, along with the necessary overnight gear. The guy who fell from 7FJ had micro spikes, which probably contributed to his fall. The snow this year is more like mid-August snow, and is quite consolidated even under direct sun. So I would recommend crampons. For 7FJ and Maude, there is no need for crampons because you don't have to touch snow, but you do need crampons to descend snow slopes on the way to Fernow. On Fernow proper, it is easy to ascend without touching snow. There are no crevasses, so no need for ropes when descending towards Fernow. Everything else is easy scrambling. Make sure you research the routes on summitpost. I didn't and wasted a bunch of time route finding on Fernow and Maude. For Maude, the West Couloir option (I did this) is quicker and more direct than the standard route. Although I wore running shoes, a light boot would have been better because of all the scree/loose rock.
As for timing, I climbed 7FJ first and then Fernow in the evening on the first day. I then camped in the basin below Fernow proper. By doing it this way, the climb up Fernow was done during cooler evening hours. Also, the next morning I was able to ascend the 1000' out of the basin and get to the upper slopes of Maude in the shade. A definite perk on hot days.
