[Elecraft] 2.7 vs 2.8 Defense of 2.7

In defense of 2.7 five pole filter as a preferred choice please note 
that when comparing the filter attenuation curves, the 2.7 skirt has far 
better attenuation out a ways on the the slope.  The 2.8 in that region 
has lots of responses in that region.
Yes I know that Elecraft says that the DSP will handle every thing more 
than 30 DB down, and I believe them, but I feel more comfortable with 
the 2.7 vs the 2.8.

So my opinion is also to keep the 2.7 and spend the extra money on a 2.1 
or 1.8 or 500 Hz filter.

Aloha,
