I've learned (and this is just my summation) that there's a learning curve to scratch boxes. They're pressure sensitive and can be a headache until you really get the hang of them. I ran one occasionally last year (2 actually: spring creek and older SS) and found that if I did things properly, they were just as good as a good box call. However, when a bird started closing the distance and my adrenaline started climbing, I'd have to put it away. Still do the same with a pot call occasionally but not nearly as bad/often. I just switch to a diagram when things get tight.
