I usually rig them weedless using offset shank EWG (extra wide gap) hooks. The top worm in fig. 4 of ianglers's link shows it, but I would suggest going in to a store that has some bass fisherman working there (like Fisherman's or Sportsman's Werehouse) to get a demonstration.
I've learned that the best way to weightless rig is either by nose-hooking with a #4-1/0 (depends on bait length and diameter) circle hook or wacky-rig with an O-ring to attach to. Why?...Senkos and the good relicas' secret is that they shimmy at both ends on the drop; kinda like vibrating a pencil held between the thumb and forefinger, altho not to such a degree. No other lure that I know of has this seductive action. It's positively spooky. By T-rigging, employing a jighead or even using a hook that places the sharp end far back into the body of the lure, you eliminate that action at one end and reduce it at the other. Such styles of rigging will work but IMO not as well. Try the ways that I've suggested, you may agree. Gamakutsa, Owner and probably some others make a fine weedless wide gap hook that works well in the weeds.
