I’ve noticed that to have really noticeable results with Bliss fields one needs to have some lower aspects of the level of consciousness scale well integrated.
This was the only explanation I could find to explain people selling so many copies of Exalted States.
So if my theory holds true, the best field to achieve a blissful state is the field that will help you integrate the thing you need to integrate the most, right now, to climb the level of consciousness scale. I will post how I would do it today with the tools we have available. You will feel some blissful moments on the journey, but keep in mind that to consistently feel bliss as a state you will need to do some work.
To win the ego battle you can use this very nice meditation by the Sapien Medicine crew. Of couse Ego Dissolution is mandatory.
To transcend mentalization I recommend meditation as a practice, but also with The Interconnection Of Everything series
The Devil Reversed also tends to help greatly on this stage 
Transcending the next stage (Love) is a bit difficult and takes some time, but doable. My first recommendation is to bruteforce it with Conceptual Realizations. Other mandatory fields here are The Wisdom of the Dying, Ace of Cups, New Perspectives, Vibration Series, Shatachandi Yagna and Love Graviton.
Once most of the Love you experience becomes unconditional, you will start experiencing inner joy, and here you start to feel Bliss more consistently using fields like Exalted State, A Dream of Purity and The Entwining Worlds of Beauty and Joy.
When people talk about feeling Bliss as a state, I imagine this is the point they are aiming for.
Other must-have fields like Blueprint of Life, Crucible of the Past, Smart Cord Cutter, Love Gratitude and Appreciation will help you greatly in every stage.
