Don't know if it would make that much difference.

Between revision 1.0 and 1.1 I've removed ~14 90 degree fittings (12 out of them were in the EK sli link) and it didn't make much difference in the flow at all.

Right now I have only total 3x90 and quite a lot of 45 but I've seen somewhere tests that 45 do not affect the flow much so I don't think this would improve a lot - beside 45s would be replaced by similar bends in the tubing.
