I don't know I don't like those 3D style props like the 18-6W. They are too heavy and I don't like the way they make the models fly.

But if you are hitting the rpm ranges then theya re OK.

To me the 18-6W seems like a bit much....but if a 120SC is turning it up in the right rpm then the 140L should as well. A really strong 120SC will come close to the power of the 140FZ or 140L...I would say about 90-95%. SO yes it should be OK. On the 140L I like the 15-12 and 16-11 maybe a stretch toa 16-12.
