Going from a P360 with a hard spring years ago to a Japanese stick was difficult for me.
Honestly, it still is slightly harder for me to do certain things on a Jap stick because they’re so light and sensitive. Fast flies are one of those.
This is an awesome battop by toggleme that adds a nice amount of weight to the stick that fast flies and the such are smoother and more effortless on a Japanese stick. I highly recommend at least giving it a try. They’re only $20 to get the stick, the converter, and the harder spring.
