The 200/2L IS is a wonderful lens. Bit on the heavy side, though.
Mount Hua? As in Hua Shan in Shaanxi? I was born in that area, and my parents used to tell me all these crazy stories about how they used to trek up that mountain in the dark with their friends and how they knew people that fell to their deaths because the paths up the mountain were so shoddy and dangerous. When I head back there this August, I'm definitely making a trip to Hua Shan.
