Your opinion: does our mesh violate rule R07??

We have a dumper robot that has a square hopper on the top. The hopper is a frame-like skeleton with mesh that is zip-tied to the skeleton. This mesh keeps the balls in. We also have mesh on the inside of this structure that funnels the balls towards our two side-by-side wheels that spit the balls out. We have 3 types of mesh that we have available. One is mediocre, one is really light, and one is heavier. In an effort to loose weight, we switched to the lighter mesh, but then remembered that there was a rule about entanglement. Rule <R07> It basically says in a big paragraph that if the judges think that someting poses as an entanglement risk, they will ask you to remedy the situation.

We compiled a list of stuff that this rule says would invite closer inspection by the judges:
-the judges think it poses a risk
-easy penetration by object less than 4 sq. in.
-nets, loose rope/wire, lots of fabric, etc.
-not mesh with 1/8 in. X 1/8 holes
-not firmly mounted
-performance on playing field shows evidence

Dementions of our mesh:
light, black mesh: rectangular holes, 1" by 3/4"
green, middle weight mesh: hexagonal holes, side-to-side measurment: 3/4", corner-to-corner measurement: 7/8"
heavy, black mesh: square holes, 3/8" by 3/8"

Because it is of the opinion of the judges, we would like to hear other people's opinion. Do you think our mesh is violating any of these rules? What do you suggest we do?
