The Cicada is literally a double Locust:I'd take any Locust over a Cicada 2A at any point in time.
"The Cicada was introduced amidst rising tensions in 2740 by HartfordCo Industries in an attempt to capitalize on the growing need for BattleMechs. At the time Bergan Industries had cornered the market in light recon 'Mechs with their Locust and HartfordCo's only prior experience was building communications and targeting systems. Nevertheless the company designed their 'Mech to compete directly with the Locust by making it just as fast but twice as large, allowing the Cicada to carry slightly better weaponry and give it an edge in physical combat, all while keeping costs down."
