This is one of those nonsense debates... and mesh is only part of the culprit like said above.
And really... complaining about noise... I'm not even gonna digress...
If the plastic spur works for you then great and keep using it but after breaking your 1st plastic spur and you get someone else to help set your mesh that doesn't have problems with the plastic spur... and break the 2nd one.
Then do yourself a favor and get a metal spur and don't listen to what works for others, just worry about finishing races.
