I purchased a new pair of Technica Cochise 130s to replace my Cochise 120s from a few years ago and the minute I got them I removed the stock liners and put in my ZipFits, then did a little heating to make sure the cork gets into the right places and wear them a bit flexing around (I put the stock liners in a closet). I was just wondering if there is any reason I should try the stock liners first? I figured since I have the ZipFits and they're wonderful to just go ahead and do it the way I did. Any thoughts?
