Why would it be hard pressed? It has the ability to have 4 independent channels. If you remove the 2 jumpers and use 4 Power House 180s, you will have 40 amps at 18V available.
The original question is similiar to whether you want an all in one computer or a desk top set up. Personal choice. The ZW-L is all in one. Big and heavy. Using a Power House with Legacy Power Master is discrete and you build up to the capability you need.
You still run conventional, but remotely with the CAB-1L or CAB-2.
I have the original ZW-C with the power houses that connect into it. It is light since the PH are under the bench work. I run conventional and command together. I rarely use the handles. Everything controlled from the CAB-1 remote. I do run accessories off the inner channels, so the short handles are useful for minor adjustments on accessory voltage, but if your using them for mainlines I contend you would never need them. G
