so the difference between the two would be a sort of counter ballanced tie? If I get it straigt, HIPS is a bit cheaper, makes nicer better cut lines, but is not s resistant as ABS that is is a bit more expensive, pulls out are a bit less crisp, and it becomes yellow in the sun. It's take and give, but they both have advantages and inconvinences don't they? So how to make a choice? I have not yet had an armor yet so how can I choose?
