Definitely octopus hooks.
The large ring of a siwash does not accomodate the leader as well as a hook designed for the snell or "leader loop" knot.
I've also messed around with "Finesse Wide Gap" as a top hook but Rayray has it right with both the distance between and the glo bead between the hooks.
As far as inserts and twinkle skirts go, it's personal preference as I've had good luck on both "gussied up" hootchies with the inserts and "naked" squid with a thin herring strip tucked up inside!
