[Unanswered]  Xtend Purple/Cherry

Is it me or does the xtend Purple/Cherry driver spring is a bit loose rather than red, grey and black colour? Someone told me he also got xtend driver with the  colour and he said the spring is more loose than the other colour. Can someone confirm it for me?
I have a red one and a purple one. My purple one definitely has a weaker spring than the red one.

My friend also uses a purple one, and the spring is also just as loose as mine. I haven't compared it with other colors since that's all I have
