Almost finished laying my tumbled yorkstone setts which loks similar to the indian sandstone setts you show on your website.
Not sure whether to use a rubber mat on the wacker. The setts are relatively soft so i guess the rubber mat would be safer.
Is there any disadvantage to using a wacker with a rubber mat fitted.

I'm not sure of the sett you're using, but for uneven concrete cobbles the mat is a must, and start the machine at 25% strength, and then slowly add power. Our cobbles are generally rated at 30 to 40 MPa compressive strength, unless your setts are much weaker (below 25) you should be fine. Just be careful.
