M_Boats: anchors

I'm about to order a Bruce 11 pound anchor through West Marine for my M15. An 11 pound Bruce seems rather overkill and too large for the M15 but I don't want to go through another overnight anchoring experience using the Danforth . The Danforth is great for San Francisco Bay where I daysail but I can't get it to hold well on overnight trips to Northern California Lakes. Past postings indicate that it's impossible to locate an 4 or even a 8 pound Bruce. Is it possible to find a 10 pound CQR? Any help will be appreciated since West Marine has a 4th of July sale coming up next week. Thank's, Rich Cottrell "Really" M15, Menlo Park, Ca
