I see from your profile (is that your profile? It says Israfel, not Robyn?) that you don't have an epic. If that's right, then yer setup should probably be a lot like mine.. If you do have an epic, replace Selo's Song of Travel with Shauri's Sonorous Clouding.
Tuyen's Chant of Poison
Tuyen's Chant of Frost
Tuyen's Chant of Disease
Tuyen's Chant of Flame
Selo's Accelerating Chorus
Selo's Song of Travel
Solon's Bewitching Bravura
Syvelian's Anti-Magic Aura
4 chants to bring down your weakened enemy quickly (you'll usually wind up with an enemy between 10 and 20% health, unless you like to cut it really close, in which case you'll often wind up losing your kill before you can break charm, in my experience), 49 Selo's, of course, Selo's Song of Travel to break charm (you don't want to be swapping in a flute while you do this), and of course charm. You could also use dispel to break charm if you wanted, but I keep it memorized in order to deal with snared or sow'd enemies, which I sometimes come across.
Overall, I haven't swarm-kited much over my bard's career, though I tried it early on when I got my first charm, and again at the 39 charm. I've only begun using it a lot since 51, now in Planes of Power. Here, the enemies tend to act just like I want them to, and the areas are nice and generally free of the type of adds that I don't want to deal with. Them flies in the Plane of Disease are a good place to start learning, for example.
A warning about using Selo's Song of Travel, though.. This should be obvious, but it might slip the mind at some point.. Make sure you are not anywhere near the enemies when Song of Travel takes hold, so they cannot break your invis (and hence your speed), and make sure you are at least 4 seconds away from the enemy (and preferably more) when you start casting Selo's Accelerating Chorus again, because you'll be slow for 3 seconds between invis break and the new song taking hold.
And I'm no expert, but ey, if ye need anything else, advice on any other places I've discovered, send me a tell; I'm on Xegony. *Grin.*
