I'm sorry, but you still miss the point. Any tub can be customized to deliver a deep tissue or soft tissue massage. I know for a fact Sundance as the ability to oscillate or pulsate. Most jet faces can be turned to determine how much pressure you want coming out of them on any spa. I fail to see the point of needing a new jet pack to fit someone's needs when you can just as easily move to another seat. We'll just agree to disagree, because personally, Bullfrog in my opinion is not a top-tier spa. Plus, the original post already expressed they weren't keen on Bullfrog as their first choice. So debating it still is rather pointless.
