As someone interested in learning caves, I have a choice. I can train with some high level GUE cave instructors who teach in backmount. They are very well reputed and their training is second to none. It appears however that backmount is becoming a thing of the past when it comes to caves so I will be spending a lot of money learning from experts whose methods are already becoming obsolete. I should then find a side-mount instructor and train with him/her. That certification may not have the same "brand value" but it side-mount is a superior way to get into caves.
Can anyone please explain why one would be a better choice than the other? Thanks so much.
