I personally prefer to stand, particularly when on defense. However, I do take a look at the people behind me and if there is someone who is elderly or disabled and cant stand, I will do my best to sit. But if the people in front me me are standing and I cant see, well I will get back up and shrug it off as "I tried". And I agree, if you are someone that prefers to sit, the 100's are not for you. It's unfortunate for those that like to sit, but I dont see that changing anytime soon.
