Depending on the size of the bait, I use half. I like the tail half better because it lays on the bottom better but it really doesnt matter. I've caught keepers on heads and tails. At Astoria I sometimes use whole baits since the fish are typically bigger. If you go to your local grocery store you can sometimes find smelt (not Columbia river smelt) and they seem to work fine. They are smaller so use the whole thing and they are cheap.
Don't forget to use scent and if things get slow stomp on the bait

. Seems to help if the guts are hanging out! Good luck.
edit: Didnt notice your location at first. Go to Cost Cutter here in Mac and they usually have some of those cheapy smelt.
