I’ve poured/injected for a few years now. Always used Bears Baits products, but last I’ve heard, the store has apparently closed due to the owner having heath issues. Haven’t ordered any supplies for a while as I’m stocked up, so I don’t have a recommendation on what brands to use now. Yes, it can be time consuming, but if you enjoy it, time isn’t a factor that I add into my “cost”. However, unless you find a particular mold for a bait that you can’t buy in a package, you may be as well off to purchase plastics off the shelf.
