I'm quite good 14 years old shooter I can make about 70% of threes and my shooting is fast. Some people says I shoot little bit with both hands, in my opinion the guide hand only supports shooting and makes it more balanced. I tried to fix my shot it was really uncomfortable and I didn't make even 50% of my shots. What you think, should I start it all again or keep my shooting technique and be in top 3 shooters in my country.
It depends on what you want to do. Since it's summer you could go back to the fundamentals and develop your shot again. Or you could keep your old shot. It doesn't matter how perfect your shot is to be a good shooter, what matters is the practice you put in shooting the same way every time. Look at Larry Bird for example, he shot crazzy with elbow out and above his head. Yet he was and still is one of the best basketball players.
