We have 2 CQR Anchors.  a 65lb (+?) and a 50 lb.  We wanted some variety in our choices and were impressed with everything we have read about the new Rocna anchors.  A different design, but we can't find anything bad about them.  Of course.....we haven't used it yet.  
The Danforth anchor, 22 lbs, is the emergency stop anchor.  It will be mounted on the stern rail.
Rocna 25 (25 kg...or 55 lbs)
