I don't think there is such thing as a "perfect" waking action honestly. For instance, my favorite waker is the ms slammer. No 2 baits will run the same no matter how much tinkering you do with them. Some run perfectly straight, others roll on their side a bit, some will dive a few feet if you want, others not. I have several and they all run differently but all get bit. Its kind of like the old school warts (annoying if you're the OCD type but they work)
Oh, and has anybody tried the IMA Roumba? It looks kinda cool but I've yet to try one
