yip, very nice...
TEC's is the big reason yes, being able to fit large-ass fittings in close proximity to another is another reason, as well as helping the block a little bit in regards to flow-rate,

I'm running 9 rows as to his 7, reason being that I do not need an O-ring.

this is pushing it a bit though
