Thanks for your input, y'all.
It's frustrating ... since here in the South snow is rare, I don't really need the 10", but considering that 10" seems to be the classic height (since it's always the style shown when you see the models in the LL Bean catalog wearing Bean Boots), it's hard for me not to be tempted to choose those! Catalog photos can be VERY tempting to go by when choosing style!
