1)那麼first呢?好唔好用?
2)m120的彈簧同ms120又有咩分別呀?
each company do have their own way of marking their spring... so it doesn't means 2 difference company made 120 spring are the same... so you have to study for it...
if you look into Xystema one M120 spring will give you around 1.5J...
1st Spring I never tried it at all... so no comment at the moment...
