Well, there is the iceberg block to compare it with, although I doubt that will tell us much. I think you should make your variations and find your best one, then send it to BillA for testing. Some people might consider having it tested as proving one person right or wrong. I look at it as throwing more info into the data pool. Sponsorship is available to help defer the cost of testing non commercial blocks, details can be found
HERE. It used to be a sticky but has since been moved to "General Cooling Forum" and has slipped into oblivion 8( If you decide to go this route, I'd be willing to help and hopefully others would too. There hasn't been a block of this genre put thru the wringer yet. The results would be interesting.
peace.
