I spent quite a number of years in this system. If you want an authentic Vism. experience and Vism. redefinition of jhāna, their system is about as authentic as it gets. Sayadaw is a highly skilled meditator, and an impressive individual. The circles I moved around, the Bhikkhus were very strict and scrupulous about keeping vinaya, highly virtuous and I greatly admire their character.
But also having spent many years, tens of thousands of hours meditating with different techniques, IMO everyone is better off with an authentic EBT system of jhana. If you have doubts, at least start with EBT and get a good grounding in that first before you explore more exotic methods that complicate, stifle, and can block progress for most people.

Pa Auk: One reason there is disagreement about jhāna and samadhi is because people do not understand the Pāli texts well. According to our Theravāda tradition, jhāna practice is explained clearly in the Visuddhimagga, the Path of Purification. People should trace back to the original suttas, the original commentaries and subcommentaries, and then to the Visuddhimagga, and only then will they understand the meanings.
Guess what Sayadaw?
We did go back to the suttas and compare what it says about jhana to what Vism. says, and it contradicts it in several important aspects.
