I have two thoughts on the mental game:
I spend enough time on the practice field having a pretty good idea how I should be throwing. But I still have occasional early and late releases, the early releases drive me insane they come with distance lost, but late comes with more distance and offline no harm on an open fairway, and they actually feel good. If no one is behind me, I throw a second disc that normally works out as a good throw to get it out of my system pick it up, and play the first disc. A tree hit on a solid throw or other objects no biggie throwing offline in the fairway, it happens. On the 18th tee or practice field I always make sure I'm wrapping it up with solid throw, I like leaving with confidence. I did have a shank on the practice field a few weeks ago with a mid of all discs. I walked to the disc to get it out of my system and head, brought it back to my tee area, and threw it again, all is well.
Despite what I've read on other threads that "its not the disc, but its you", I no longer believe that. Its possible to be throwing the wrong disc for my form or game. The past two years, and 6 months after I started playing the Star Mamba has been my primary driver great for a beginner. The past year I started feeling that I'm growing out of the Mamba there flippy, looking for something more stable. I started exploring and a few months ago I bought an MVP Orbital and loved it. Straight down the middle with fade, on an occasion I might tail off too soon. This past Friday bought a Wave, worked with it on the practice field, threw it on a wooded course Monday, more distance than the Orbital, with fade splitting most fairways. The Mamba hasn't been my main driver in about a month, but stays in the bag for turnovers only. I now have 10 MVP's in my bag and love throwing them from a 6 speed to a 13 speed they feel all the same throwing them, and its the first time I've ever been able to throw a 13 speed. For my purposes I'm slowly transitioning to the MVP's in my bag, but will still keep a few Innova's, Westsides, Discraft, and Lat 64 that I wouldn't think of replacing. So, perhaps some disc exploring to find a better fit.
My purpose in this long rant, that there are many variables to consider in The Mental Game. Now if I can just find that perfect C1 putter for the Mental Putt Game.
