Is there a practical difference between Lucky Craft PointerDDs and Stacey King Jerks?

For instance, other than lure profile, it there a performance or action difference between, say, the Pointer 100DD and the SK Jerk100D2R?

Yes. The Pointer is noticeably more subtle. The Stacy King jerkbait is quite a bit more aggressive....similarly to an X-rap.

When would you use one or the other?

When would you use one or the other?

I wish I had a definitive answer for you, but I don't.  3 years ago I won a club tournament on an X-rap right after a huge cold front in the spring.  My partner and several others in the club were throwing pointers and got skunked.  You would think that a more subtle action would entice fish during a tough bite, but sometimes it's just the opposite.  I'll start with one or the other, and if I'm not getting bit and I feel there should be a jerkbait bite...I may try the other.  

Same thing happened to me this past spring. We were in the middle of a cold front, freezing, and we won the tournament on a x-rap. The rest of the anglers in the tournament were using rogues, we won by a pretty big margin.
