Flat or grippers if fishing on a slope.
Pear( dumpy or long ) for distance.
Square or dumpy are good for giving maximum weight on the lift.
I don't think the actual rig dictates what lead shape or type is needed ,but where the rig is used definitely should be considered with shape and type.

Indication ,running rigs win all week long.
leadclips???............they're great for ease of switching leads till you find the one that works for you..(and setting hooks and snag work)
Inlines, semi fixed , free running and drop off are all rounders, great for bag work, but can cause problems on some bottoms as the swivel can get damaged if not a bag.
