It's up to you which size italic nib you wish to use, but remember--problem areas are easier for you to see with a broader nib. Nibs broader than 2 mm are not necessary, but I'd suggest that you begin with one not smaller than an 0.9 mm--or larger, if possible. If you can manage it, 45 minutes per day is a suggested amount of time to practice. If you feel any muscle strain in your neck, upper back, arm or hand...Stop! Even a break for a few minutes can make a difference.
I could go on & on--but I'll let you ask questions instead!
The 1st scan gives you some info on the proper size & weight of the letters and how to know how far apart your guidelines should be for a given nib.

Notice the box to the right with the X in it. If you hold your pen so that the thinnest and thickest strokes that the nib can make are made when you make an X, you will be holding your pen at about a 45 degree angle to the writing line (base line), which is correct for italic.
