Yeah, I've been holding onto my lucky jams. I'm a ways away from level 16 but I haven't been out much because Sunday the servers kept going down and yesterday it was raining. Gonna try and get out today!
Also, I think the most effective way to use the "lures" is to set up 2 close to each other. Any time I've set just 1 up I don't get much, but whenever there have been 2 that are relatively close I've caught crazy stuff.
