Guys, I said it before and I will say it again... NO ONE has been very successful using poly tops. just the fact of the matter.

Lexan/Poly are awesome at absorbing instant high pressures or shocks. They SUCK at long term mid pressure/stress situations. The cracks around the fittings and bolts are the exact same problems most of the people who have seen, made, or used a lexan topped block have seen.

They look nice and all but personally I am sticking to copper top blocks till either they get a new plastic, or find a way to avoid cracking like this. Cause in a system the thermal cycle'n of the metals that are in high stress relation to the poly will encourage MORE cracking as time goes on.

Not knocking any company who has tried this, its just a fact no one has pulled it off that well so far.
