Hi, Do you guys use your index finger or your middle finger when poping. I have always used my index finger but have always struggled to gain some real fluency with it. I have been trying my middle finger but find it feels a little weird. Some people say there is no right or normal way to do it and that it's up to the individual to even innovate a style but at the moment I'd like to at least be comfotable with the basics. How do you guys do this? Any help or ideas would be great.
