I find this pen to be an excellent follow-up to the original Titan. In my experience with this pen, the filling system feels improved, the section has deeper grooves for better control, the section has a smaller diameter, and the slight angle to the cap makes it easier to identify by touch. The ink capacity is very good, around 3ml, without doing anything special. The nib and feed are very nice! I have enjoyed writing a couple of pages so far and am very pleased with this pen. This is certainly a pen I can easily recommend to any fountain pen user, from a beginner to an advanced user. I will say the cap feels slick to my fingers. This means I have to use a slightly larger pen sleeve so it is easy to pull from the sleeve. But that is the largest demerit I can put against this pen. What I consider a must for pens today is cleanability. The section is easy to remove, allowing complete cleaning of the body. A blunt needle on a syringe is a great tool for cleaning the body. I have no qualms recommending this pen to anyone. Please don't add a version with a carbon fiber cap and plunger knob. That would be terrible for my wallet. :)
