Engine from Daily ´Nade wrote an interesting article about how to play with the SR-8.
I really liked a sentence in the “POSITIONING”-section…

Knowledge of the map is essential. Circle jump to the closest sniping spot (or the one that you should cover) and wait there for enemies. – Engine

…and i must say he´s right.
NOTE: Waiting is NOT camping!

There´s also a really nice video, captured from a Team Survior Match from iCu*. The Player tarquin is also a writer from Daily ´Nade. Besides he´s a damn good UrT-Player.
Watch and learn:
