So, what we have done is invest in one of the battery powered weed control sprayers, and I spot weed as necessary, takes about 10 to 15 minutes for all of our garden area, and I refill the battery powered container as necessary.
Also, when we had pine bark, it was 3 to 4 inches, the same for the pine straw. We removed the pine bark as it was dirty as it decomposed, the pine straw seems to be much cleaner.
I actually saw an article within the last 6 months that made a very good case for not using a weed barrier at all.
In any case I would not place either of these items over the rock, O would remove the rock and then install.
Hope this helps.

You are absolutely correct the weeds are above the weed cloth and are easily pulled. I regularly pull the weeds to keep them under control nothing will stop the weeds. I recently pulled up some stone to put in a patio and was amazed how much dirt was above the weed cloth.
