For what i head from acc shop tauke (dont tembak me)

ABS is more expensive than PU is because ABS have light weight compare to PU.

Some PU is heavy till 3M double tape also can;t hold it need screw it/lock it to prevent the skirt Fall down

Not sure abt Other con and pro, this what i know.

BTW last time i got saw yellow color one i not sure what material is it (ppl tell is rubber + fiber) The tauke show us can throw on the floor and berpulit-pulit also no break O.o
