We switched from the CQR in 2006. I don't think the Rocna or Manson were out yet, or at least wern't widely known. I did research on anchors and if they were available I'm sure I would have have purchased one instead of the Delta.
The only time I dragged in the middle of the night was in the Dry Tortugas. The wind switched, we ended up in the middle of the channel and were slowly moving in the direction of the fort. Damn,,,,, re-anchoring at 3 AM with no moon and a full anchorage is always an interesting experience. No problem but we woke a lot of people up.
