Collect Phase - Brainstorming - Alternative to Sailboat?

Hi, I am hosting a brainstorm and would like to use something like the Sail Boat Exercise. However, I gauge from the what I discussed with the participants that this might not be an effective "Collect" tool for this group. We don't really have big issues to solve, rather need to think up a new way of selling "business value" workshops, aka Design Sprints or the like, on what else is a very technical track for clients. Any ideas what I could use in this Brainstorm to run the Collect phase?
