Since changing strings after they snapped, after two sessions on the court I developed severe bicep pain which prevented me from hitting forehands. After resting for a couple of hours the pain passed though. However, I am worried about playing with them again so I want to change them to something else, but I'm unsure what. I am about a 3.0 - 3.5 player, so can any of you recommend some strings? Money is not an object, but ideally I would like something quite durable.
