Sounds good, unless you're carrying all of them all of the time. Given the uncertainty of your socks and shortness of time to check them out, carrying too many is probably preferable to carrying too few. I think I mentioned earlier that sometimes, I might take two pairs of one sort of liner (that expected to be most used) and one pair of another, so I have a bit of choice. In my case, both types are Bridgedales, the coolmax ones being thinner than the thermal ones, so providing a little variety to suit different conditions. Not exactly heavy!
