#67 looks a little clumsy. A fully filled triangle takes too much attention away from the text. One tend to focus on th etriangle only
#68 is a little better - it breaks up the colour, but actually the design doesnt work for me
#68 is really quite nice, but the certification text seems not to be set out right, spacing, location - can you make the certification text start under letter T and continue to letter R. This may then look more balanced. A little rework and this may look very good.
