jetting and altitude

I live at about 600-700 feet and the hills and back roads around here extend up to around 1400 feet, I've already installed the air filter and moved the clip down to bottom. I currently have a 115 jet which I was planning on putting in. What do you guys think about it?

btw I noticed that my stock air box already had a couple of 3/4 inch holes drilled in the top. I saved the filter and everything so I can install it before I go riding in dust. If all goes well I plan to attend the rumble on the ridge on april 5th with a friend of mine.
