Well crap, I found a bunch of UK sites a few weeks ago, one was selling the Abyss and Deep radiators but don't know where they are.
But this is a picture of one...and it looks thicker than tha BIX...and thats the problem with the BIX, it has a smaller surface because its thinner...so I think the Depp would perform better.
