I use a modified fan grip. Learned this from a Paul Ulibarri video. Take the disc in your off hand, hold it in front of you vertically with the top facing you. With your throwing hand, pinch the disc between your pointer finger and thumb (the pointer should be off the rim). Let go of the disc with your off hand. Now add the other fingers (my 2nd and 3rd fingers point slightly backwards, little finger on the rim), but not tightly. Hold the disc out in front of you on the line you intend to throw. Press down with the thumb, slightly indenting the top of the disc.....I found this important....the pressure should come from the thumb, not the pointer finger. Make sure the wrist is straight to slightly bent inward. It should also be pointed slightly down. That is the position the wrist and disc need to be in upon release.Thanks for sharing. Last I tried, I still couldn’t throw mid ranges or putters with a power grip. I fan grip putters, with my Watt and/or Dart getting out to maybe 125-150’ max. Form still sucks, but improving - hoping eventually it gets good enough I can throw them, but not holding my breath. What changes did you make to add 50’ with your 5 speeds? Probably a change I will also need - one of many.
My biggest issue was making sure I followed through. I take a long x step stride, if I don't start from off the tee pad I run out of space and "abort" my walkup....which causes my weight to be all on my front leg and stops me from following through. Follow through and HOLD the follow through. Lastly, whether you walk-up or run-up....the timing of your legs, body, and throw all have to match. I can't do a run-up....if I do, I have no clue where the disc will go when it leaves my hand. For me there is a fine line of how fast I can do my walk up before things go bad.
I find that if I 'overthrow' the disc (either walk up too fast, or "pull" the disc through too fast), I actually lose distance. Finding that sweet spot of how fast to move the body and how fast to move the disc took me a bunch of field work with one disc (I used my Axiom Hex 5/5/-1/1). The hardest parts for me are making sure I go the right speed in my walk up (I want to go faster) and pulling the disc through at the proper speed. (Faster is further - right? Nope). I find the 'sweet' spot in the pull is if the disc moves slowly until it is in front of my chest and then speed up from there (but the speed up of the disc can't be too great of a difference...just a bit faster). Lag at the beginning and have a 'hit' in the middle.
Also, if you can film yourself from the back....watch your body during the walk/run up. My instructor told (and showed me on a video) that I start slightly bent over (in a hyzer throw position), but end up straight to slightly bent backwards (anhyzer throw position). Paying more attention to that has improved my accuracy.
Commit to using just 5 speeds and less and limit your molds. Let's say you have three 5 speeds, but one is overstable, one is neutral, and one is understable. They all need different types of throws. If thrown the same, they will fly differently so it can be difficult to work on consistency and form when you are using discs that don't fly the same. I played for a month with just three putters (one was a putt/approach for tee shots). I didn't care about the distance I was getting.....all I cared about was focusing on form. After a while, I realized my distance was increasing. I went to a field and did some measured throws and found that I was throwing further, so I added my 5 speeds into the mix with the same plan. Forget about how far they were going, just work on form and hitting my planned lines.
My 'control' holes have mandos. One is a double mando, the other a triple mando. If my form is correct, I make the mandos. If anything is off, I miss the mandos. When I am just playing for fun and on my own, if I miss the mando I rethink the shot and why I missed....then I rethrow correcting my mistake...that helps the muscle memory and just enforces the right way to make the throw.
