Definitely not V10 as suggested in the book. I did finish up the prow, but not "around" the prow as the description reads which seems a bit contrived. I do however intend to return and do it that way for full value, (but sorry, not V10 value). Either way, fun problem!
The problem that I climbed is more accurately called "The Stinger Left Low" rather than "The Stinger Low", and I think the lower grade is the result of this difference. This seems to be the problem of the month and everyone has an opinion on the grade, but my vote for this climb with the sequence that I used is eight V's.
