A couple summers ago I went back up there with Max Tepfer and we reclimbed the lower pitches and placed a couple bolts below the crux section of the headwall (Scott and I certainly would have been shut down in this section on our attempt even in full aid mode, as we had only cams and nuts) but neither Max nor I freeclimbed the headwall. I believe I only tried TRing it, and failed.
A couple weeks ago I returned for a day trip with friends Mike Pond and Austin Siadak, who both helped scrub and brush and chalk and prep the top of the wall and hammer in a 3rd protection bolt at the crux plus one at the pedestal belay under the headwall where a small stance exists a couple feet left of a crack.
I redpointed the pitch (though there were 2 directional pieces left over in a non cruxy lefward section from our cleaning/bolting/rappel work.) Overall we all agreed it's possibly the best single pitch in the Enchantments, with a very sport climbing or endurance-based feel to it. Take care to sling out your gear and manage pump and rope drag. There no single killer crux if you're at least 5'8", it's just an unusual style for the mountains. The gear-protected climbing is probably .12a or so, and the crux comes after a 3- bolt long boulder problem near the top, something like v5-v7 depending on height and beta.
For the headwall in particular (which realistically is worth rapping in or doing via the west face start) I'd suggest triples (even 4 wouldn't go unused) of yellow aliens and/or stoppers in the #9 BD range, and nothing larger than a couple #1 camalots. Both obvious flakes seem quite stable and were pulled on, kicked, and knocked with a hammer. For a good challenge, and certainly the hardest route in the area, it would be possible to start via The Tempest P1,P2,P3 into the Miracle Whip finish. This contrived combination would feature 2 memorable hard pitches of very very different styles. I suspect if it does see traffic it will mostly be via the first couple hundred feet of the West Face which is a very fast and clean approach allowing for quick access via pleasant warmup.
Edit - after a repeat by Nathan Hadley and a couple attempts by other experienced climbers, this might be more likely .`13a, especially if you aren't tall.
