Silent front sprocket?

[Decoke Dave]

  I know it won’t need it with 12500 miles on my Gen 1 thou, but would I notice any improvement in smoothness, gear changes etc, by fitting one of these so called silent front sprockets. Don’t mind the work of fitting it, and they are relatively cheap, no issues at all with how the bike runs etc. I’m sure there will be a good bit of experience of these being fitted on the forum. Thanks.
