It's up to you which hookbait you use. I know a few people who love a pop up over a bag and is their 'go anywhere' set up. I personally don't use pop ups a lot but I wouldn't not use them in this presentation.
As always, try both, see which hookbait seems to be working, and stick with it. It could change from lake to lake, day to day on same lake, or even through one session.
