What are your new mics?
The shockmount shown in that pics looks like the AT8415. A good shockmount, I've used them before. Also popular are the AT8410A. A pair of either is a great start and runs around $80-100/pr.
IMO, you're better off skipping the flex-bar at SP and picking up a Shure A57M vertical stereo bar (~$50), or an AKG KM235 bar ($25).
