Both the Tech Pan and the 4125 can be very useful to nuts like me for low to normal contrast situations that I wish to create a high contrast in-camera negative.
I used the (4x5) 4125 (Professional Copy Film) this summer in the Redwoods. Not the best film for sun-lit conditions. As Drew mentioned, the highlights can start taking a hike clear out of sight before you know it. The difference between one stop exposure can create a whole different relationship between low and high values (not always wanted). Its own special rule is to expose for the highlights and develop for the shadows. Love the stuff. I find the Tech Pan is a little more versitile for landscape than the Copy Film.
