I see your point and can say from multiple experiences that suitable per-session negotiation has proven effective at setting the stage for a cold start.

My first experience with a cold start took place in Pittsburgh many years ago. It was overwhelming. Within two minutes I was hanging upside down, completely helpless and frightfully aware of who was controlling the situation. It was the real deal.

Initially, I hated the experience of being so fully controlled so quickly. Several years later I realized the experience was a gift, opening a door to a deeper understanding of what for me makes a powerful session.

I look forward to playing with someone willing and capable of diving into the deep end from the start. It's not for everyone, but there are some willing to give it a go.
