Those look great!
I also make some large/heavy spinnerbaits, up to 2 1/2 oz., but there are no Pike or Muskies here, so they're Striped bass lures for me. I began tossing big spinnerbaits years ago for Stripers, when everyone else was tossing the road runner style bucktail jigs. ( I make them too.) Just something different, and I had many times caught Stripers on spinnerbaits when tossing them for LM bass in brackish water.
I use a couple of different hooks, mostly 7/0, VMC makes one and Owner Long Shank hooks are another I really like, although they are expensive. I'll use Mustad spinnerbait & O'Shaughnessy hooks too in 5/0 for some of the weights.
I use the Do It Style H, and the modified Poisontail molds in the larger sizes, and will dress them with bucktail or silicone skirts.
Spinnerbaits are certainly a versatile type of lure with many uses.
