I have only put my hands on one SMA Heavy Duty Brushguard and I did notice how it was not very solid. If you do want something that is very solid and offers much more protection I make one that I am particularly proud of. It mounts directly to the frame and is extremely solid and durable. It is available in different materials and finishes. I am having one electro polished for a customer today.
Good Luck
