Macro Help - 90mm + Raynox 250?

has anybody used this combo? Wondering what trichimes look like with a 2:1 magnification... will it be enough?

Have a D800 and a Raynox 250. Looking at a Tamron 90mm macro to pair with it.

Does anybody have any sample 2:1 magnification sample images of trichomes they can share as a reference?
