ahh - suddenly all is clear!... so to see the whitewater & cascade at their best we need the rest of it at over 1m....
and the 5003's disadvantage is that it is more restrictive than a 6000 - or even a cascade.....?? but the C/W vs Headloss graph flatters the less restrictive blocks (since the balance of the system would be a higher proportin of the total resistance and so a given pump would give a lower headloss to a less restrictive block...) so then the 5003g is better than i thought -
