Does the #70 Uncoated Text feel similar to 14pt Uncoated Paper, the difference being only the weight? Is it possible to write on either of these?

The 70# uncoated text and 14pt uncoated are made by the same manufacturer. So they have the same exact finish, whiteness and brightness. The only difference is one is a lighter text weight paper and the other is a much thicker stock for postcards. They are both perfect choices for being able to write on.
