The Komomo II is a bit insane really. I must admit that when I first used one about 18 months ago that I didn't really like it. Being used to fishing deeper diving, faster retrieve baits, the Komomo II initially rolled on it's side and came back at me hugging the surface and on it's side. It wasn't until a little later that I really figured out that the only way to retrieve it is slowly!
There is no weight shifting system inside the bait, which means that it rolls very easily from side to saide. Massively in this case - which is the reason it loses stability at higher speeds. Keep it slow though and the Komomo II comes back at you in a shallow, and wide 'S' shape. Beaudy!
