Personally, I like a wire through as it is cleaner and I don't have to anything to it when it comes out of the mold. Less touches, less work, less time to make. BUT if you have not dialed in the exact placement of where the hook eyes need to be placed, I'd recommend screwing them in to dial in the weight and balance of the lure. You can also set the hook eyes in your mold and cast them in. Lots of options.
Microballoons will start to have a greater impact on the physical properties of the resin when you exceed 100% by volume. People use the microballoons up to 100% by volume without any issue of strength or failures. Wire through designs can also help to reinforce the lure when extreme durability is required.
