    I am trying to understand the strength difference between using WR400g, which to me is a 12 oz roving and two layers of woven cloth 200g or 6 oz.

    Are they super close or not even? Finding the WR400g fairly nonexistent in these parts.

    I can get WR600, but then I'm heavy and it is the outside layers..
