First topic, questions about the hidromax models - by: Leonidas

Hi everyone!
First of all thank you for all the info shared by this community
I am looking foward to buy an hidromax but I found confusing wich pump should I get (seems I am in the middle of the x30 and x40 models)
I am about 7.5 inches in erection bone pressed (not to hard and laying down)
And about 5 inches girth

So wich pump should I get?

And also, its there is a big difference betwen the xtreme versions? I mean, does it ger annoying pumping with out the ball?

Well, I will wait for your answers before getting the unit!
Best regards
