Wow, a buddy and I have been working on this route (he nailed it last Sunday), and we were approaching this move very differently. Holding the rail and high-stepping the left foot on the lower piece of the rail then working up to the little lip. Wondering if this works out better? =)

Good beta shot- this is definitely what worked for me, and the previous commenter was spot on for what I was trying beforehand. The high step to the rail with the left foot is a much harder move.
