  Congratulations on the mirror!  I well remember my first 6" mirror.  Why not
share a few comments on how it went.
  As far as the bigger mirror, I suppose a case can be made for the compromising
effects of light pollution on light grasp, but in my opinion a bigger aperture
is always nice to have (not withstanding portability, cost etc. etc.).  You can

tougher'  ;)  ;)

 My concern would be the jump in size as far as the working of the mirror
blank.  I don't know your situation or experience level, but a 16" mirror is a
*LOT* more work than a 6".  Oh baby!  ;)  ;)  On the other hand if you have the
right situation, attitude, and dedication, go for it!!

Clear skies
