I agree with Kostya. If chess gives you 2 hours for a game, why play it as a blitz in 5 minutes? You'll make more mistakes. I'm sure with a 2-minute limit, your slow-thinking opponent would do the same, but within the allotted time.
We're not having a race here, but enjoying ourselves.

I suggest a poll:
1) 10 minutes is not enough for me - 15 minutes
2) I want to play comfortably with more time - 15 minutes
3) Who's the slow thinker: confused: , am I the slow thinker: confused: , definitely I'm the slow thinker - 15 minutes
4) He's the slow thinker, but I'm not, but I still want more time - 15 minutes
5) Or your own option for 15 minutes :smile02:
