Unfortunately, there are training schools that use production-line training techniques and still try to force their students into using only the Weaver stance.
The more I study and train, the less convinced I am that there is any "one true and holy" technique.
There are things that work well, things that work a little better in some cases
, and stuff which is total crap.
IMHO, the complete defensive skill set consists of developing good default behaviors, which cover most of the bases, and then (if time/money/inclination allow) filling those in with other skills for specific circumstances.
Iso is probably the best overall default technique. IMHO that's where 80% of your training time belongs. Weaver and even CAR certainly "work", and have their places ... just not as general/default techniques.
