Hi all, I absolutely love the feel of writing with Pilot V5 HiTechpoint. But I can't use any ink I want in it. It comes filled with a large quantity and once ink is over, it is supposed to be disposed off. To be sure, it can be opened with a plier and refilled, but that also works only a couple of times before some damage or the other happens. So I have this question for experienced fountain pen users here who might have used this pen too - which fountain pen comes closest to Pilot V5 HiTechpoint in terms of writing experience including nib thickness (I think 0.5 mm)?? If it is within my budget, I will acquire one. Also, I will have this knowledge with me when I buy pens in future. Thanks in advance. Sanjay
