Route Info on upper Long's

Greetings MP,

I just want to solicit information on a variation of Kiener's Route on Long's that a friend and I did (rather unintentionally) over the past weekend. The picture below shows the regular Kiener's route in red, and our route, more or less, in blue. Basically instead of following the edge of the Diamond, we went straight up a small couloir/slab just climber's left of the huge dihedral. The climbing was maybe 5.7-ish with a good bit of rotten ice and snow, and it topped out at a small, snow filled notch on the south-east side of the summit (where the ridge from the notch couloir joins the summit). We found a couple old pins and saw several old rusted cans wedged in various nooks and crannies. I couldn't find any info on it in the RMNP guidebook. If anyone knows what it is called, who the FA was, the consensus grade and all that jazz, I'd be very curious to know.

Thanks!
