For what it's worth, 4wd with omnis does have a small front-biased turning radius. They are vulnerable to being pushed, but they are probably the simplest drivetrain a team can build. Low resource teams should look into this drive if they feel they don't want to take any chances with their drivetrain this year. And really, when do you want to take a chance on the most important part of your bot?
