I probably will, especially since I don't think I'll watch any of the later seasons (except for 13 which I plan on watching live this summer). The only thing about 6 is that it's been spoiled for me so I already know who makes the final 3. However I did like Janelle a lot, and if she's even more dominant in 6 than she was in 7 than I guess I have no choice but to watch it. As for Howie, he just seemed like a dumb bully to me in season 7 so I didn't actually like his character all that much. He had his funny parts but overall seemed pretty obnoxious.
I'll probably start it in a few days when I realize I'm not currently watching any tv shows and have too much free time on my hands.
