I have been trying to avoid adding to the bedlam, but then you drop a mini-bomb 
like this "pending" variable passband crystal roofing filter.

It would appear to be a good idea not to fill up the roofing filter slots until 
this is no longer pending. I assume it will be similar to the K2 filters?

This is one of those little "gotcha's" that makes me wait until the dust settles 
to order.
