I got the Katoolahs this year too.
Never bothered with getting spikes before, but late ice last year had a day that the ice was so slick I had to use the auger like an old person uses a walker to get around. I’ve known people that have had SEVERE head injuries from falls on ice, and if it’s a choice between $52 for good spikes or more lures, etc. GET THE SPIKES.
