Im guessing bigger as well. All three are at least 130" it looks like to me. I'd say the first one is definitely the biggest, I'dguess right at 150". Second has good mass but short main beams which is significant as Ed said, but we can't see the entire rack and it looks likeone tine is very long,outta the picture,I wouldguess 135". Last one is tough to guess, but I'm going with 139"-ish.
