What size should my caps be in my episode reviews?

I'm preparing to do my review of 3.01, which will be posted with some caps from my recording of the episode. However, I'm having trouble trying to decide what size the selected caps should be. I know some of you are on dialup like myself and appreciate clickable thumbnails, yet the temptation to have larger images makes the review look very pretty.

So I've decided to ask all of you what you'd prefer. Keep in mind that I've made over 1,200 caps of this episode and only a very small number will end up in the review. They will also be much smaller than the caps that will be featured in future picspams. I also haven't decided how many caps will be featured in the review. Last season the cap counts were anywhere from 60 to 180. So keep that in mind. I just like to include some visuals of the key moments to help illustrate my reviews.

Please, let me know what you think. This will effect all future reviews.
Edit: I need this info. as soon as possible as I hope to be posting my review either late Tuesday or Wednesday.
