I did buy both aluminum and plastic the difference in thickness between the two is hard to see you would have to use a micrometer to tell so i dont believe there would be much if any pressure drop.As for duability i left it in fuel and ethenol for a week no effect and did have it in the oven all good.
Only went the plastic due to the smaller holes.
If you can get 1/8 in aluminium I will give that a go and do logs on both.
