The Jepp folders are excellent value. I have had my set of two 2" and one 1" for 10 years and there still going strong. I reckon they'll last my career out. I have the Duraflow as I think they are better than the Leather for durability. As for the Jepp clear sheet protectors, I use them and they are fine. They do however have holes drilled to match the plates so you do have to open the rings to remove the chart you want. It hasn't bothered me though.
