Thanks for your ideas.
I think #2 should perform better but nothing better than making a couple of each, test them and start producing the one that performs better, that shouldn't take more than a day to test.
The guy that was supposed to deliver the copper plate that will be used to make the tops today delayed it, he said it can take to friday to get here
These things should be ready a long time ago and I'm working hard on them, they wont be ready this week as I tought they were, it sucks depending on other people...
Thank you
