I'd personally make sure the main bit of the hooklength was supple - stiff ones can sit up at an angle.
i can't see the pointusing critically balanced bottom baits with stiff links - ok if they are pop-ups.
resting on the bottom or popped up? i'd go with resting on the bottom, or in the silt - its where the natural stuff is, but loads of people swear by popping it up - the choice is yours!
