The reason it is a pain is that you are putting the hooks in ***after*** the mold is poured. I bet a production shop could be set up where you have pre-rigged hook packages in place at the time of pouring, elminiting the "rigging" process altogether. My concern is that they would use cheap hooks.
The only problem I have with sluggos are: when you finally get one to come out perfect this happens on the first cast....

They need to pre-rig one with top quality hooks, a soft stainless coated wire braid so it is flexible yet cut proof and have built in weights. It would not be cheap. Until they do this, you are probably better off making them yourself and re-using whatever you can.
