Which is the best pen for UPSC Mains?

For me, the search for perfect pen had ended last year after I tried 

Rorito Trimax and

Hauser Tech 5 

These 2 are the most reliable and comfortable for me. Never faced any issue except 1 Trimax leaked out of 10 pens that I bought. 

Since then I have never looked at any other pen :)

I used mostly Trimax (rorito) during mains. I guess only one paper was with Hauser as it was my secondary choice. But like I said earlier, for me both are equally good. 19-20 ka farak. Rest assured you can see the ink colour for yourself and be the jury :) ✌️
