Since I already have the Ten Tec 221, I'd prefer to see such a filter with a 400 Hz bandwidth.  The INRAD 753 is one of my favorite filters, since it seems to be a good tradeoff between insertion loss and selectivity. Tweak it down a hundred hertz and it might be the perfect match for the 765. 

As I mentioned in my earlier post to the INRAD list, using two 765's-- one in the roofing filter and one downstream as a 9 MHz IF filter might also work pretty well.
