Both venue's have their place.
Yes there are some things you can really only be sure of if you've tried them with live ammo and someone who can shoot.
The majority of training is better off in the TA. I'm talking takeing someone from day one up through basic ability to fly & fight.
Face it, 95% of all that we learn we end up having to teach ourselfs anyway.
Yes we have people who help show us the way. But in the end it all comes down to
A Understanding the concepts involved.
B Stick time to hone reflexes and be able to do it all without thinking about it.
(When you see "this" you know you have to do "that" to counter)
High end training or 1 on 1 practise you can do anywhere.
TA, DA, CT, or main. It just takes some minor adjustment to methods.
That leaves us with the majority of training. People from day 1 to maybe 6 months. Here the TA shines, simply because you can squeeze more air time into each session. Without someone constantly having to replane because he got shot. You also have the advantage of being able to start out working with fuzeman or myself, and work your way up with several of the trainers.
Each of which has his own strenghts and insights to pass on.
