I started using Cascade Complete pacs when I got the new KDTE304G.
They worked fantastic.
I had a few light loads though, and on the very light soil loads, I DID have some excessive sudsing issues with the Complete pacs.
So I got a box of Complete powder, and I custom dose that with my soft water on light soil loads, and that seems to work great.
So I now use the pacs only for full, heavy soil loads and they work like a charm.
