Again not to be an ass, but a simple search would have told you that the first two- LA CON and Urkle- are notoriously low yielders. Great smoke, but not yielders.
Search each of those and you will a ton of grow reports on each, from there take a look at what is close to your set-up and base you decision off some research.....have a feeling white widow will win this one.

It's not that no one is giving direction, its you aren't looking hard enough. There is plenty of searchable answers. Opinions are "ehh", which is why I told the poster to look at grow logs- find actual info and go from there. Every strain can yield well to most peoples standards simply with enough training and light.
Here are links that took about 5-10 minutes to find. Look past the first page of the forums, or use a forum search tool to find more threads, as these are often just a few pages back. Should be at least 30-40 pages to skim through with these links. And this is just the tip of the iceberg, I didnt wanna spend hours digging up threads. lol.
