which type of live rock is best?

[Doug]

I can still tell the difference in mine, but it makes no difference. Its all the same basically. I have 12 yr. old Florida rock, thats much less porus then the Fifi, but still as nice. I think my large pice of Marshal, is one of the less attractive. I recently had a friends large pieces of home made rock in my tank and it was just as nice as any other I have. As a matter of fact, when its covered in growth, it may be nicer.
