Looking for large maps

[Blaster Cheif]

I can't find many maps using the full middle level of Sandbox with the guardians blocked. So far I found Snipedia which is really good as is Blood Gulch. Large maps seem to to work lag free in 8v8 custom games and I see so much potential

Can anyone advise me where I can find large sandbox maps?

Thanks for taking the time if you can

Does it have to block off the guardians? I have a pretty big map in my sig. Click teh pic.
