Dyneema for lunch anchor rhode

[Stumble]

I am not really to try it on the big anchor yet, but on the fishing boat we often anchor 5-10 times a day while working a hole. Since my dad is starting to have problems picking up the 1/2" nylon, and chain leader we use I have been thinking of switching over to a full dyneema line, and getting rid of the nylon, and the chain. I appreciate I will kill the cantinary, but for this application it seems like lighter weight would win out.

Does anyone have thoughts on dyneema (probably amsteel blue) as an anchor line?
