Lol, Dave The cables are definitely Half-Block issues.

As well, 3% doesn't warrant continuosly having blocks destroyed - 4 out of 5 again and again is not 3%

I'm also (relatively) sure that Mining Lasers don't do a 3% - At least in the current version of IC2 it's 100% Drop, and i'm quite sure it hasn't changed.
