Pros & Cons...
Any underlay will help reduce noise levels.
Any track / ballast that's glued down on top of the underlay takes it all virtually back to a zero noise reduction
So what's the best option
It really a matter of personal choice... Use an underlay that deadens sound without applying glued ballast or put up with the rumble and have realistic looking ballasted track!
