A good parallel setup for Luke would be something like this (not sure what his current order is, I went off older pics in his log to determine this order).
Thanks for suggestions and diagram.
Changes look actually much easier than I though there would be (no need for another res, etc.), so I actually might pick up some fittings and single tops in the next couple weeks out of curiosity.

That's pretty much the order I have - so basically what you're saying is that there is not enough restriction in the loop for the serial setup to benefit it and the parallel setup would do the trick and improve the flow significantly?

Also, considering what the current values and scaling in series are any ideas what numbers for the parallel might be?

For example currently:
1 D5 = 130,
1 DDC = 160

2 D5 series = 200
2 DDC series = 200 (I've adjusted from 205 for GPU serial to parallel change)

2 D5 parallel = X?
2 DDC parallel = Y?

I realise it's hard to tell with that many variables but perhaps interpolating from some existing tests I could have some idea?

P.S. Sorry for double post it - didn't notice this post before replying earlier.
