Since I've lost a total of 3 anchors over the years, and before I purchase another, I wanted to ask what type of anchor do you use on the Big Rivers? What type of anchor have you had the most success with, ease of retrieval, not getting stuck, holding power, rope/depth ratio, etc....? I have used the Fluke style, and Chene anchor. I am considering either the Richter Anchor or Digger Anchor? Is the Fortress Anchor "retreivable"? In other words, can it be pulled in a "reverse" motion to dislodge? And, what about the Claw, are able to pull it in a reverse motion?
