Good set-up; The point about spacing away from the CF is valid, however the plastic tubes I suspect requires additional nose weight to offst it's mass.
As far as the spacing issue, if one can get the antenna element away from the CF equal to or greater than the cross sectional thickness (of the stranded portion - not including the thickness of the jacket material), you have effectively reduced x4 any (if there is any) reciprocity/association with the CF boom. So a layer of your colored tape placed (you could split it lengthwise - just wide enough to displace the antenna) on the boom first, plus the jacket material thickness itself would be (electrically) adequate. This is most critical where it runs parallel in and outside the fuse (the exit point is @ 90 degrees or some nearby value)...
