Never noticed that as some high cask strength whiskeys don't have the legs some weaker ones do. I look at how runny tge legs are. While alcohol content creates the legs how runny the legs are depends on various oils contained in the whiskey. I was told the legs were related to the ester and other aromatics in the whiskey. I tend to add water a drop at time to whiskies that have slow running legs.
