I can vouch for Starfish Scuba out of Boynton. Have done one of their Goliath trips on the Castor every year the past 5 years or so. Great site and never disappointing in the activity of grouper congregating there. Problem for your group, would be the depth as you would hit 100' on this wreck. Send a message, or check their site, I think they show which dives are scheduled there, and I know occasionally they double dip that wreck so you can certainly get your fill. I saw some posts from last weekend that the grouper are already starting to hang out. Enjoy.
