Aluminum Water Pump...which one?

moosoMember

While my ZF is out for a rebuild (they haven't moved it in a month...boo hoo) I've been looking for things to do.
A shiny new high volume aluminum water pump sounds good! I've found four different ones. Most claim 30% more flow. One claims 30% more at low RPMs and normal flow at higher RPMs. One claims to block off a passage for more direct flow.
Is there a "preferred" pump for the Pantera? Is the pump really going to improve cooling, or is the improvement so slight that it is a waste of time?
I have a stock radiator with larger "pusher" fans. I live in Colorado and traffic is becoming a problem. The car has come close to overheating on a few occasions, during the summer, but generally does OK.
Thanks, Mooso.
