Ohhhh....the daggers are flying now. Hey Valley, just a quick little added note. I was given a suggestion some time ago that I found quite helpful. I bought myself a little jewelers loup for cheap off a popular "auction site". It's a little handheld high power magnifying glass used to look at jewelry stones, etc. Once I began to inspect my freshly sharpened saw teeth with it, I could see my sharpening mistakes and inconsistencies much clearer. End result.....chains that cut much better and stay sharp much longer. I was shocked when I saw how dull a freshly sharpened tooth could actually be even when it looked sharp to the naked eye. Biggest revelation was that even though the point "felt" razor sharp.... I had not ground it down to where the point was in the plane of the cutter top surface. By missing that detail, I was having the same problem you described.
