M_Boats: Anchor size

Hello all, I have a pretty standard equipment M17 from 1987. The boat came with a nice Danforth anchor when I bought it 15 years ago, and the anchor has served me well.  For reasons I am ashamed to explain, that anchor (together with its rode and chain) are now at the bottom of a lake. I will not provide details :) But I want to replace it, and I was curious as to 1) Do most Montgomery owners favor Danforths over other types of anchors?2) What size (weight) Danforth do people use? I have seen them in 8lb, 9lb, 10lb, 12lb, 15lb weights, etc. Thanks! Andrei.
