Kapalabhati and bhastrika are the same breath infusion, except that kapalabhati is the preliminary stage with stress/focus on the exhale while bhastrika has stress on both the inhale and exhale. These I feel are the best for raising kundalini and surcharging the subtle body. Please if you can check my book Kundalini Hatha Yoga Pradipika to see that bhastrika is the top notch pranayama practice.
All the standard methods of pranayama are good. A yogi should try every one if he can learn it, and then decide which best suits his needs. In my view bhastrika is the most rapid method for infusing prana (subtle energy) into the subtle body so that kundalini will be surcharged and aroused. Why?
Because if that is acccomplished, the subtle body will go into pratyahar and then when one sits to meditate it is likely that one will do samyama easily. Samyama according to Patanjali is the progression of dharana into dhyana into samadhi.
However I have no objection to the use of any other pranayama, provided there is a result which accelerates the practice and causes the yogi to achieve the silencing of the chittavritti.
It is a good idea, that if you do pranayama, make a video of it and get it posted on line, so that other yogis who are not expert at it and who may learn from it, can get hints about it.
Remember that Patanjali listed pratyahar introspective state after pranayama. That is a hint that the practice of pranayama should give the result of pratyahar or at least it should make it easier to put the mind into pratyahar.
