Re: COT 320

Hi Bob,

I also use varying sizes of COT320, and I've certainly noticed a  
difference among the paper sizes as well.  I always wondered about  
that.  The newer batch I'm working with doesn't seem to have any of  
the earlier problems mentioned here,  about which I'm really happy--  
but my recent experience suggests this paper is not as consistently  
predictable/reliable as it once was.  I do wish paper manufacturers  
would leave well enough alone. :)
