Is the Choice Between Roll Bar and Non-roll Bar Anchors Necesarily Binary?

 A roll bar is just a righting mechanism. Non-roll bar anchors can have wings that go pretty high.

 

 

 

So, when do wings become a roll bar?  Unsurprisingly, this rolls upright just the same as a roll bar. In fact, the wings are probably a little taller than they need to be.

 

Why would this possibly be better?

• Grass and trash can slide up and out, rather than become trapped.
• The turning action is better, because the wings are canted slightly inwards.
• The drag is slightly less, thus deeper burying is possible.
• The upwards levering of the toe is less because the useless mid-section is removed.

Downsides?

•  Not as strong. High strength steel is a must.
• Slightly more complex manufacture. 
• It does not solve the roll bar fit problem.
• Could more easily snag the rode unless well buried. 

Just brainstorming with you.
