Think about _why_ you are doing thin vertical slices. You started with large stories which are too big for a single sprint and typically stretch across multiple sprints. The reason this is a problem is that it's hard to plan, and no value is delivered until several sprints later when the story is eventually completed. Horizontal slices solves the first issue but not the second (nobody is receiving value from just the back-end of a large feature). Vertical slices solve both issues. If your vertical slices are so thin that you can now complete several per sprint and have introduced coordination problems between team members, perhaps they are too thin. You don't need to go overboard, you just need to solve your original problem (stories are too big). Bunching vertical stories together is fine as long as you are still completing the bunch inside the sprint, and delivering value.
