I climbed this once and was entirely uninspired compared to all the other offerings nearby. I wouldn't climb it again. But oh well. It's there, and an alternate way to access the second/third pitch of Midway etc. if Midway and/or South Crack are bottlenecked.
But then again if that's the case, you can always climb Rainshadow.
Again, I don't want to be critical of those people out there expanding our Leavenworth climbing options on their own time and money. I'm just not sure it was necessary to forge a line up in that exact spot. Lord knows I've spent a lot of time at Castle, and to me this route just seems sandwiched and out of place.
Just my stupid opinion.
