Look, you can see if the gate is different by making a 360 motion. Youll see what the stick draws, if it’s a square, an octagon or even a circle. If your gate is not square you can change it, Its easy to find them. You might even be able to buy one very cheap from someone who likes octa gates. Since every jlf comes with a square one, there must be many of them lying around. Maybe someone in the forum could sell you one for a good price.
The JLF on a TE is quite loose and not as clicky in comparison to many other sticks. But I recommend you try to get used to it, because once you do it’s a really great stick. It will last you long and parts are easy to find.
It’s a horrible Idea to keep an EX and sell a TE. You can put another stick in your TE, or change gate/spring in the JLF to suit you better.
Give your TE at least a month. If after that much time you still don’t like than start thinking about changing something. You’ll almost always need to adapt to a new stick (or any controller for that matter), even if it’s better. Take that time before you take conclusions.
