i personally love 100% hets.....i think of them as codoms (with the visual recessive being the super form).
a normal het may or may not be valuable depending on the sex and type of recessive gene it carries. for example male normal het albino, this is not an ideal candidate for breeding albino projects, so it could be difficult to sell to a hobbyist. female normal hets on the other hand are win win. more hobbyists want them, and if they don't get sold, you can raise them for future projects.
to get higher chances of producing visuals and ensuring all non-visuals are 100% hets, i plan to limit my pairings to visuals x hets.
