In your posts for survival endless you said for diggers, planting spikerocks in the last row is best

I tried this, and as you can see below, my digger stepped on the spikerock, turned around (towards my house!) and I lost at only 19 flags because of it! Just thought you should know, to add clarity to your tips, that they are not consistent solutions for diggers. Is there another soution you can recommend?
