As detailed in my posted account, I had previously climbed U Wall free to Dance in 85 making what many might agree, the second free ascent at that time.
However, like Peter and Hamish, I felt that climbing the whole route with the Roman Chimney finish was the real deal as this constituted a free ascent of the entire "Grand Wall" of the Chief.
I led all of U Wall and the Roman Chimneys free in early July of 86 taking one fall on the 10c lieback above the tree, ironically the easiest pitch on the route.
I don't know the details or chronology of subsequent ascents or whether people climbed the Chimneys finish.
U Wall with the Chimneys finish, climbed free or with aid is bar none, the finest route in Squamish.
