I use a 15lb Navy Anchor that I have had for 15 yrs or so now. Used it on my last 20' fish n ski and I have it in my 1880 Angler. If I were in the market to buy a new anchor I would get a Digger. A 15lb anchor with 40 lbs of muck and yuck on it gets pretty heavy to pull in. The diggers are self cleaning when you retrieve them.
