Nice job quadzilla! Adding new meat to your legs can deffinitly increase your bodyweight - your legs hold some large muscle groups. People with underdeveloped hamstrings can easily add 10 pounds to their bodyweight by finally blasting their hams.

But whether they are too big or not - I would say keep at 'em cause you will make a good impression and stand out from the others more. Just put some more of those intensity fundamentals to work on your upper body so it catches up. Lookin' good.
