Now that I'm armed with a couple 'dos that work with a huge fork, I'm interested in buying.

I'm thinking I could use 4-5 prongs/tines (or even up to 7, as in the Baerreis Cygnus); this could be translated into a comb width (and fewer prongs?) of around3". Even 4" is a possibility!

Prong/tine length probably needs to be around 4-1/2" to 5".

Usually I go for a contrasting colour to my dark hair, but since I'm looking for something quite large, I'm thinking something that blends might be better, a dark wood or darkly coloured dymondwood.
