I make my benediction on a Tallis Godol & hence absolve my Tallis Kotton from a Berocho.
This sounds to me like a very simple solution to whether Tzitzis on mesh fabric qualify for a benediction.
Every Jewish male should be wearing a Tallis Godol whilst reciting his morning prayers, so that no-one feels discriminated Chas v’Sholom based on their marital status.
