Hi Peter
This is really hard to explain but I will try. I don't know if we are just playing with semantics here when we talk about rolling. When you work a gamma and it does that characteristic slash across the surface, the lure actually rolls to its side at the point it turns. As you continue to pull it through the water, it then slashes across to the other side. At the point it rolls, a predator underneath can actually see the sides of the lure.
If the lure doesn't roll, the gamma wouldn't have that sharp slashing action. When you have a direct connection, the action is sharper as you have a more direct connection to the lure so when you pull on it, it reacts directly. When you have a swivel, the lure will be permitted to continue to roll a bit more than if you have a direct connection.
All gammas roll but the bigger ones roll more in my opinion. You should see a 250! I actually believe the rolling action is one of the major factors in its success. As you would know, the only fish which turn to the side are those that are injured. I think the gamma mimics this very well.
I hope my explanation is understandable. As I said, its really hard to explain.
Brandon, do you mean that it is supposed to roll? Or do you mean that the direct connection prevents it from rolling?
I think tha Gamma 200 is rolling quite much (at least when I work it! ), where as the gamma 140 that Mr. Konishi is working in the Carpenter video doesn't seem to roll at all. It just wobbles which I do prefer over the rolling action.
Thanks,
Peter
I often use a swivel with Gammas just for convenience sake when changing lures. I do believe you get a better and sharper action by tying it directly on though. The reason for this is that the action of the gamma is such that when it rolls, a directly tied connection will see the lure react more sharply versus a swivel.
