Will not comment on this thread other than pasting a reply from another site I frequent by a friend of mine. His response was to someone who always asks questions but never seems to take the advice. This is not directed to the OP but to all who ask for help and ignore it when given by qualified individuals.
Robin,
Good luck in what you choose. Some of the programs that are published have some pretty major credentials behind them.
Only you can choose what's "better".
There is no right, there is no wrong. There is no single size to fit everyone.
If you find someone you want to emulate to try and achieve their results, go for it.
If not, keep on searching.
I will tell you one example and I'm punching out.
For nearly a decade, I worked reasonably hard at becoming a "World Champion" in the competitive duck calling circuit. In that venue, there are human judges who score competitive routines, basically 90 second long "songs", and the highest pointed caller at the end wins.
Some folks in that venue would emulate a role model and strive to reproduce their results. This is particularly true of the RNT crowd, many of whom emulated John Stephens, with very good results.
Others would approach judges after each contest to get their comments. Each judge, would offer their own personal preferences. The callers were constantly chasing their tails, making adjustments to address what they were told by last week's judges, in an attempt to better please next week's judges.
A retired callmaker (Wendell Carlson) had a phrase called "The Search for the Magic Flute". This was the phenomenon of competitive callers changing up techniques and getting new calls - constantly trying to find the new trick that would put them over the top - as opposed to role modeling a world champion and striving to consistently be just like them, to try and produce the same results.
Here's the thing: some guys WANT to constantly search and be the rebel. If they do, that's OK.
But some of the most knowledgeable in the sport, once they realize someone operates in that manner, eventually choose to not spend a whole lot of time trying to help those individuals. The reason is that they know that person will run down the road and repeat the whole dialogue with someone else. Those who spent their time trying to help the magic flute searcher, wind up feeling like they could have spent their time doing something more productive.
Good luck in your quest.
