As most already know - this is a great pen for beginners! The firmness is middle of the road and the elasticity of the tip (the ability to bounce back to its original form) is good with this pen so don't be shy in applying pressure to your downstroke! As long as you are cognizant of the angle you hold your pen (not too upright), you should be able to minimize the fraying and maximize the life of your pen.
These pens are great for watercolor, blending of colors and they are self-cleaning if you were to blend (2) colors together. Check out my Instagram video posts for some examples of this!
