The one you speak of is the VMC sure set hooks. Tried them last year and had very little success, but it was also my first year really experimenting with tipup rigs so ???.
Will give them another go this year, but had just as much luck if not better on regular trebles for bigger baits.
DNR sent me an email stating that as long as the two to three hooks are 9″ apart, you can place as many baits on those hooks as you want. Regulations don’t regulate bait, but the hooks used. 2 fatheads or smaller shiners spaced apart produce when others dont! Look it up in the regs if ya want.
