In addition to this forum, one of the best places to learn the small things is at competition matches. Places like F-class, egg shoots, g-hog comps have a lot of people who will have a lot of different equipment and use a lot of different techniques. One of the peculiar things about the types I go to is that they are more of a social activity than a competition.
It is also a good measuring stick. There are no excuses, no whining and no fudgeing. Your score is what it is and it is all your fault.
