Need insurance for my Airsoft field? (General Liability and Accident with Participant Coverage)

Run an airsoft field for a couple seasons and I need to get the insurance right instead of renewing whatever the last guy left me. CQB structures, wooded field, walk on weekends plus rentals, real claims come from someone rolling an ankle in the treeline not the BBs. I know I need general liability but I keep getting told accident with participant coverage is the piece that actually protects me, is that right and what should I push on when getting quoted?
