I will, because it's the truth. The most beneficial reviews, opinions, endorsements, etc... for any product, come from regular people that have actually benefited from that particular product. By "regular" I mean average, not already established pros. Cameron Champ led the PGA in longest drives last year. If he comes out today and says his success stems from the latest and greatest 2019 driver design by Ping, it doesn't mean much, at least not as much as if Joe Blow tells his buddies, "I'm getting an extra 25 yards from the newest Ping driver."
But this doesn't mean professionally endorsed products aren't great. It just means a better test or endorsement is when the majority of average users say, "Yes this product is good". And when Stan's book becomes available it will be subjected to this type of test by those who puchase it, unless it won't be available on Amazon, Barnes and Noble, BAM, etc...where any Joe Blow can find it, purchase it, and give their opinion on it. And of course your opinion matters, along with other CTE users here that can actually say their game has improved because of CTE. That means more than any pro endorsement.
