I hesitate to jump to any "new" anchor technology: I've used Danforths and CQR for many years, and then I hear of the Wonderful New Bruce, that is a Miracle Anchor that holds in anything, sets anywhere... Then people start using it in Real Life and results are not so miraculous. Then along comes the Delta - another Miracle Anchor. Again... not so miraculous.
So I think I'll pass on the Miracle Rocna anchor, at least for now.
I did really like my CQR, so I'm leaning towards the Delta, especially since you can't get a new genuine Bruce any more.

Yes, the Rocna has a great following, for good reasons, but...
* The Delta comes up clean, no mud. I like that.
* The Delta is easier to break out vertically. I like that.
* The Delta requires a little more weight to creat the same hold, but is still the same price or cheaper per pound of hold. Noted.
These statements aren't always true, but few general statements about anchors are.
Now for a breif rant. I tire of those who call the Delta a plow, because it isn't. It is a wedge, designed to place the soil in compression. It couldn't be more different from a farmers plow, which is designed to lift and turn soil. Just the same, I wouldn't compare a Rocna to a Northill, though the angles are very similar.
Tie a 35-pound plow to a horse and see how he feels about that. He'll know it's different.
(no knock-offs. every expereinced sailor has seen bad ones of every style. small differences in geoetry or fabrication make all the differernce.)
