Chuck,

I'm certainly no expert.  But, I was facing the same delema, which 
filters to buy.  I have my main rec filled with 6, 2.8, 1.8,400 and 200 
filters.  When I recently added the sub-rec, I only bought the 2.8 and 
200.  So far, I've been pleased.

Good luck, you'll get a lot of comments on this one.
