I was trained proper caving SRT in my local caving club. I hang out with guys who do proper rescue and use "proper" rope technique (multiple ropes, industrial equipment, etc) and I have developed my own style based on my inate desire to keep things simple and as easy and mindless to operate as possible (thus keeping my wits about me).
I recommend getting 2 books, which contrast each other in many ways but both contain good gems of info.
1. On Rope (Padgett, etc) American rope technique - very interesting and full of ropewalking and mega drop stuff
2. Alpine Caving Techniques (Marbach, etc) Light rigging, single rope, etc, etc.
Personally, I'd only consider industrial techniques if I was painting a bridge.
The best recommendation is to go caving with people who are experts and drag you along with them.
