A pen for the big hand, Pilot Dr. Grip.

I was recently asked to recommend a pen for user with big hand.

I know that there are many pens out there which are suitable, but the one that came into my mind is the Pilot Dr. Grip.

I have been using this pen on-&-off for the past 2 years, but I personally find this pen very comfortable to write with, especially with prolong writing.
