I am running the Neg Pressure and find it pretty good once you get over the fact that leak proof in not necessarily air proof (this might entail new fittings, an extra tightening of components, etc). The majority of my loop is soft (16/10) but it does give an extra sense of security. The best thing is actually filling the loop via neg pressure, one of life joys

The diagnostics are pretty detailed too.

While waiting for my bits to arrive I took the opportunity to upgrade my Wi-fi to version 7 via a TPlink EAP772 powered by a Tplink SG2008P

My Pimax Crystal Light arrived and it and my RX7900XT are getting along pretty well in IL2 - (fab optics and detail, pretty uncomfortable) - Solid upgrade from a HP Reverb G2 V2
