Great read and great advice. I've found myself in the gear gathering and hoarding mentality lately and not nearly enough time actually doing anything to further my shooting proficiency.
I'm in a similar situation as you... I used to shoot often and well.. then I started reading all the forums and searching for the next best thing, and my shooting has suffered.
I would also add, that taking advice from some people who have never seen you shoot isn't always the best approach. Sure, some experts give advice that is considered best practices, and the fundamentals are important to get right... but unless they actually see you shoot, you should take some of that advice with a grain of salt. What works for others may not work for you and vice versa.
