so, if i get this right...
situation: it is real hard to find low volume, high head pumps; e.g. eheim doesn't give u alot of choice, with the jump from 1048 to 1250, head increases only slightly, volume doubles.
most commonly found pumps show the same characteristics (via aqua, maxi jet...)
with that variable in the total equation almost fixed (or goto iwaki or little giant, both really expensive and hard to come by in europe); it is almost always cheaper to find a high flow rad (reading bill's graphs right, hopefully) like the serc, or easy to find big momma. + a high flow block, with some performance to match, like the old swiftech with 1/2" barbs , or (not seen it on bill's graphs) new swifty 462 with lets say 1/2 barbs (looking at design, no maze, just a hollow chamber with some turbulance).
from a block's point of vue, it needs good c/w over the whole flow spectrum + a low pressure drop / flow rate. to have a max performing system, taking advantage of the low head, high volume pump.
am i getting this right, or wrong?
