It should also help flow rates by a small small small bit since the longer the loop is the more restriction it has.
Of course your absolutely right, what I was going for was the same concept in circuit analysis, in that in a Y or parallel setup, resistance is cut in half across the section of circuit, unlike in series where resistances are added. Sure flow is also (nearly linearly cut as well at this point) but the EK VGA blocks are High resistance/low flow turbulence blocks, and are really really effective.
The Y adapter, like martin had stated, getting close to his Whye, was significantly more slippery than many other types of fittings...
Sadly, length is a by product of tube bending, The only way to make some of the angles was to follow the natural curve of the tube and induce a slight twist to keep it self stiffening.
Notice at the pump the zip tie trick to get the outlet port to make a gentle 90 degree bend, thats cause the NZXT phantom case has 2x 120 mm fans right at that height... also had to mode the case and put the 200mm fan on the outside, just too much consumption of internal space in its natural habitat!
