Re: K3 vs. K7 - Initial Observations

Walt,

Thanks for your input.  My only resistance has been that VFA is not available larger than 
13x19, and I had hoped to offer one paper through all sizes.  Perhaps I'll just have to use 
it when I can.

I somehow had missed that USFA sheets are double sided.  I'll get a box and try it out.  

Thanks!

Best.

Josh
