Acetal or Plexi?

[iKettles]

I'm looking at the EK Supreme CPU block and I'm just wondering whether I should go for Acetal or Plexi? Is there actually a performance difference or is it just for looks?

Acetal.

Plexi can crack under stress (eg- screwing in the barbs too tightly).

plexi looks way better just go carefull and you wont break it

unless you're a moron Plexi won't crack in the lifetime of use in the majority of cases.

I think in the case of being unfortunate enough to get a bad block that doesnt show signs of leaking during testing but only after a bit of wear....Id get an acetal one.

I went for acetal 'sure does look purrrrty' (works well too).Don`t think it makes any difference performance wise
