If I were you I would grab on or two that are the most diffenrent in size and weight from a bomber or some other lure that is available in plastic. Why buy a $20 6" swimmer when you can get that for $6 in a bomber. I would go for the 6" swimmer that's 1.5 oz. or 2 oz. because it gives you a little more variety in your bag.
You might also take a tip from the "experts"

and put some 6x hooks on a bomber to get a similar effect. That will make them heavier and possibly adopt some the characterics you get from the heavier Green Points.
