I don't recommend getting a windbreak. My car came with one, but I haven't fitted it for years - doesn't seem to make any noticeable difference to wind noise/turbulence at speed, but it does reduce rear visibility and doesn't look that nice. Don't forget that on top of the cost of the mesh panel you will need to get the rest of the kit (new roll bar covers with channels to fit the panel, storage holder for in the boot lid). There is also the pair of perspex covers that come with the kit to fill in the roll hoops - these stay in when fitted - so I have never taken them out and therefore have no idea what benefit they alone bring.
