I hope that teaching "zero to hero" isn't standard practice for him - if it is, it would be a VERY negative point.First and foremost I will say that Brian Kakuk is one of the most liked and respected cave divers, explorers, and cave instructors in the world. He does teach students what u guys call “zero to hero.”
Curious about your experience now even via pm if you don't want to speak in publicI highly recommend you talk on the phone or skype (or whatever) with the instructor and see if you guys "gel." Instructors who consider themselves hotshots, who are "social media sensations", and charge almost DOUBLE as other people charge (so they can be Dora the Explorer traveling the world) are a no-no to me. I learned this the hard way.
