I am relatively new in WC and don't know much. I see many people use Laing D5 / Swiftech 655 pump and therefore I think it is a good choice for me. But I just come across something called Petra's top, which, as I understand, is a mod for Laing DDC-2 / Swiftech 355 pump, which seem to be able to tramsform DDC-2 into the performance king in its catergory..... how should they compare and how should I choose between them?

The DCC2 is giving better all round performance in mnost loops these days (depending on components in the loop) according to most reports I've read. But lately on alot of the high-end water cooling forums there's been a lot of failures of the DDC series pump...........
I'm happy with my little old Laing D5/MCP655, but I'm also running dual loops so the restriction isn't that much of a factor.

The only thing that matters in a WC loop is head pressure. The DDC-2 w/ Petra's beats the D5 in this category. The more restrictive your loop is (such as running multiple blocks or blocks that are really restrictive), the more you need a pump with lots of head pressure.
The only downside to a DDC is that it has a slightly higher failure rate than a D5 pump. You can keep yourself safe against such a possibility by having speed fan measure the RPM's of your pump and perform a shutdown if either a) temps rise above a certain threshold or b) RPM's fall beneath a certain threshold.

Usually you can tell if you have a pump that might fail, because they will need a tap or a shake to get the started. If it needs that, then just RMA it.
