I hope that you are adressing me... as I cant seem to follow the ''thread'' somehow.... and hope that Im not answering a question that you addressed to someone else.
I use my spade on the Mid Atlantic Coast and Chesapeake. Obviously it works GREAT in sand, mud, hard pan and moderate grass and have found that it will reset almost immediately on a reversing situation (There are only 3 rocks on Ches and Jersey coast.... and I know where they are!). Ive found it useful in loose shells where my old CQR was hopeless. Ive been in situations where the old CQRs would simply plow along the bottom but in comparison when anchoring in the same locations under pretty much the same conditions the Spade will dig right in. I''m used to the ''foilbles'' of the CQR.... extra long scope to set then shorten the rode, etc. and have a good gut feel by now that I can anchor with much shorter scope with the spade if need be.
