When you start to climb Langley from the top of the pass there is one trail. When you get to ~12,300' there are 30 trails. Stay as far to your left as you feel comfortable...further left the steeper it is.
When you get to the mountain, look for gaps that are ducked. These are short class 3 sections that will save you about 20 minutes each way. If you feel uncomfortable do this, just hang a left until the ducked class 2 scree slog appears.
