No need for the high stability reference. The basic one is also a good
piece of work.
The 2.7 filter is fine in ssb.
For CW/data add a 400Hz roofing filter or so (depending on your normal
operating BW). You will need it in a busy band.

The K2 BFO will shift slightly if the bottom cover is deformed, but that

sitting on its feet properly. If you have something under the K2 or
have it on an uneven surface, it may be deforming the bottom cover
