Yeah get copper.But not ordering from dangerden would be the best thing to do.
I have been waiting too long for my maze1 I ordered, with no confirmation that it even shipped.They also got the shipping address wrong so fedex lost it
They dont answer e-mails either...
Yeah go with the copper top.
I have the lucite and It cracked because i put a flare fitting in it
That is why I ordered the maze 1...I need a strong block that can hold pressure
