I've always run Cegorach's Revenge as well. First of all I sort of viewed the skyweavers as a tax when I was first learning the army and was disappointed by them. However then I tried investing more points in to them and have settled on 3 bikes, 3 haywire cannons and 2 zephyr glaives.
They're probably the best ranged anti-tank in the codex (I don't use allies) I like 3 haywire cannons as provided I dont get a bad scatter I should be able to drop transports such as rhinos without requiring additional fire from a second unit.
I only run with 2 zephyr glaives just to save points really. Obviously I position the bikes to juggle wounds around as best as possible with the intent that the bolas biker is the first to die to protect the zephyrs.
I use my bikes as harassment units.
Early game: Move around the flanks trying to open transports and work their way forewards
Mid game: Go after the hard to reach targets in the backfield like thunderfire cannons etc. As most of these backfield units aren't really high model counts or particularly good in CC only having 2 glaives is quite sufficient.
Late game: As my squads are usually below half strength by now my bikes start to team up with the troupes often eating overwatch and providing hitting power that the troupes have lost through the battle.
Drawbacks to this build:
Jinking makes them useless for shooting (mirage launchers are fantastic!)
Remember you can throw the bolas in addition to firing the bikes weapon. 4 small blasts before charging can put the hurt on infantry. Even if I usually get at least one scatter on to myself
