Dust Shields

Onto my third one in two years of ownership, its a bit ridiculous, its the Same rear corner. So the question is do I need it.

Will the increased dust cause the abs sensor to becone damaged or do I need to just watch out for damaging it when cutting it off.

The garage cut one off before and soon after my abs light came resulting in a new hub.

Cosmetically I don't care.

I did come up with a genius idea of drilling the shield and cable tying it to various components in place, it works for my track bike after I've crashed. Sadly they all snapped or caused it to rub more. That's an hour of my life wasted.
