I've been wondering the same thing Munge, ever since I got the Spencer book about 14 years ago. Hiking around up there a few years back to get a look at the Incinerator was when I discovered the Runnel Vision Wall. I was just up at the Incinerator a week ago today. We climbed Supernova to get over to the Incinerator. It is a complex area but the trail in was easy to follow. The roof pitch on Supernova is a classic for sure, more like 10a. Nice to have an old 3.5 or a new 4 and 3 #1s would have made it more straight forward, gotta remember to protect your second. We did it in 3 pitches. The first and last pitch were ok. Climbing a route on the Milky Way Wall seems like the best way to the Incinerator for sure. Would be quick to run up Crossing the Milky Way, although from just looking 4 stars seems like a stretch. Non the less it did look fun and easy and a good approach to the Incinerator. It would be a grunt up to the Incinerator from the Milky Way even though they are real close and there is a good trail between. On the Incinerator we climbed Up in Smoke which was fun but felt hard for the grade. The 11b, Burning Man to the right felt easier. We ran out of time after that to check out other routes around the left side so never got a good look at the Routa de Fruita. I wanna get back there to check those other routes out on the Incinerator and the Afterburner Wall and Inferno Roof looked good as well.
