BigHawgBaits, I've been doing this a long time so I'm going to try to help and give you some advice at the same time. The closest mold you can get in a Do-it mold would be the bullet head which isn't what the hack attack jig is, to make that head you have to have a custom mold made from a mold maker and it has to be different enough not to infringe on Strike King which means you'll have to have it designed. Being that you are just getting into this I can assume you don't want to spend $300 to $500 on having a 2 or 3 cavity mold made so this is where my advice is going to come in. If I had guys asking me for the hack attack jig I would direct them to the nearest tackle store, really. Custom baits is about making something different that what you can buy, and even though we can all buy the molds the bait will be different, if I gave 5 people the same molds to make a bait, I will bet a million dollars I'm going to get 5 different baits, and that is what I love about this. Now, every now and again a design comes along that we want to make for ourselves but can't due to trademarks and stuff, in that case we roll with what we can but try to make the best we can using what is available, for a head design like the hack attack it needs to be custom made. Now, that said, there are numerous other heads that work fantastic, so what kind of jigs do you want to make to start off? If you are going to fish brush then I would suggest the Arky style jig, the Trokar Arky is an awesome powerful jig and there are other hooks that can fit besides the Trokar they are designed for. If you are going to fish grass, then go with the Snootie jig or Bullet jig, these are both great as well, the Snootie makes for an awesome compact jig that comes through grass better than any jig I ever used before. If you are probing deep rock there are numerous football heads to choose from but approach making jigs not by what you want to copy but by what you need. Look to see where the jig will be used the most and go from there, you can ask questions here like you just did and we can help but there are limitations and special heads that are developed by big companies like Strike King usually have protections on them so you or anyone else can't make a copy. Don't let this get in your way, like I said, lot of really good jigs to choose from, let me know what you will be fishing and I'll help you out.
