Skirmish fleets that fight aligned are very ~no mistakes~
Try to have perches on the target before you engage on it. The first four and a bounce are essential, six is best for maximum mobility on grid. If you do not have those perches already made, a far bounce and a combat prober (best to use an alt) can do the job. Use both and you are gold. Use interceptors and you are pro level for skirmishers. For fighting with skirmishers in FW, it is best to use range+speed over many of the slower but harder hitting skirmishers. Talwars, SDestrels, snoop bills, Boi Heretics, Crows, etc. (flycatcher too though I haven't seen them yet.) All of these doctrines are light missile, what is transversal doctrines that rely on range and effective kiting to win. They are far far more effective in lowsec than proper skirmishers simply because there are no bubbles and much smaller ranges and targets. Skirmish Naga's won't do the jobs better than skirmish Talwars in low. They use range, and speed/sig tanking to avoid enemy damage, the best doctrines are ones that are cap stable or very good in one area or more. They rely on alpha as well and take time to hit their target so splitting stacks and calling volleys work well once you get the hang of it. FC's job is to anchor and call targets, drive them away, kite effectively and prioritize fast tackle so your fleet doesn't get snatched.
There is no better way to learn how to effectively skirmish and these kinds of fleets are often cheap, easy and loads of fun while still hitting well above their weight. =)
