No no, this is the single player section.
I used to have a heater shield for the longest time. Majority of the game in fact. See, I would use it in sieges, and by the time I got onto the walls, the shield would eventually break and I could switch to 2h. Good way to keep the proficiency balanced.
Nowadays I use a thick huscarls round shield:
1) To show off my wealth and power,
2) Because it's such an unbreakable shield,
3) Because I wanted to look like my troops, and lastly
4) My coat of arms looks so friggon good on it.
Only downside is that I don't use two handed as much. I do sometimes though, if there's no archers nearby.
