I remember when the new $20's came out and asking several non-collectors what they thought of the new note. I was almost shocked at how many people noticed the razor thin paper. It was the most common feedback I got. When the $10's followed I was equally surprised that the paper was so poor. Its good to see they've improved the $5.
And yet I predict that the poorer paper quality is actually good for collecting these notes because when the same notes wear out so quick the higher grades will be all the more difficult to find. So far the prefixes have been fairly regularly released with few short, or rare inserts. But the $10 FEP is hard to find, and there will be others I'm sure.
Time will tell I suppose.
