I have installed many Gracoils on customers shotguns, no complaints so far. I also have quite a few on my own shotguns. I am not sure why a deciding factor should be the ease of making the length of pull adjustment. It only takes a few minutes to change the Gracoil LOP. I mean, how often do you halve to change it? Changing from summer to using a winter coat and back again in the summer, a couple of changes a year at most and it can be done in a couple of minutes. Installation on a Gracoil is also much easier, less cutting into the end of the stock. My two cents worth. Regards, Bob
