I have taken a look at many of those sites before, and again today. I have also used the oregon website. The trouble I have with any of these is how do you determine which one to buy. Even Oregon offers a myriad of choices with different features, and I cannot figure out which one to buy or which one I would be getting if I ordered it. Oregon has LP D DP and a bunch of others. To add to that, I find spools of chain for sale, that may be great or junk, but no way of finding out what they are (oregon 11-H for instance). I am a tad anal-idiac and have created a spreadsheet for the chains I use. But putting all the different brands on there is unrealistic. I have found it easier to walk in and tell the guy at the counter what I have and let him hand me the chain. Do you just memorize the ONE chain you like or use and always buy that one? Any hints? JB
