Also true that regular class sloops with Storm Chaser upgrades are a good choice against them, was the case in potco anyway as I haven't tried it in tlopo yet.
Not only a good choice but excellent. I made a regular maxed storm chaser just because of LS's. Advantage is the extra speed and maneuverability compared to heavy warships. Though I certainly respect their broadsides - but balance is, that a good broadside takes half of the LS's health - with a very fast turn and 'offering' the other broadside ... I have sent many a LS on a fast escape. Regular sloop is a true versatile ships in svs and so far my favorite.
