Damn Ed, don't get your ******* in a bunch. Over on the metal shaping sites everyone shares information and provides feedback, or recommendation for alternate methods. At the end of the day it's still your sand box to do as you please, but it's all part of that challenge to learn the things you need to learn. The way I look at these things, it's been my experience if you haven't failed, then you haven't tried. The nice part of the feedback the metal shaping guys give, is the failing part gets limited by learning from others that have been there done that, especially when attending the workshops. Learning different methods may not apply to what you're doing today, but may be just the ticket for that next project. Has less to do with whose way is better, but just like the shrinker-stretcher set you bought, it expands your bag of tricks to have other options, helps accomplish more in less time, or helps to tackle a new challenge, for continual improvement in your methods.
