I've played the game off and on (More off than on) since I was 13. That's 30 years if I'm being honest. In the past few years I have swapped darts probably close to 20 times and the one thing I find is that I can throw just about any shape or weight relatively the same. According to DartConnect, I have about a 39-42 3da in 501 and about a 2.0mpr in Cricket. The one thing I find I am CONSTANTLY struggling with is my rhythm / arm placement / proximity to my face. More or less everything to do with my throw that happens before the point of release. I tend to come to "set" differently, arm speed varies, how far I draw back varies. I guess I am asking if anyone has any tips on a more repeatable throw? Thanks in advance!
It's going to take some work, but make a mental checklist and go through it every time you throw. Starting with stance, bringing the arm up, aiming up, throwing, follow through.
If you make a list in your head and go through it each time, over time the steps will become instinctive and you will be more consistent.
