Strawberries are supposed to be one of the worst. I wash all my strawberries very well (and ALWAYS individually). Yes it takes longer, but I take the time because strawberries are much more pourous than other fruits since their is really no 'skin' of any kind. Then again, organic strawberries are usually pretty easy to find. Trader Joes always has them during strawberry season. They are just more expensive.
What about potatoes? I eat a lot of tubers, and I don't really find organic sweet potatoes and regular potatoes very easy to come by, so most of my consumption is non-organic.
Are you all eating organic potatoes or are you just washing the potatoes really well? Do you think eating a high volume of non organic tubers could catch up to us?
