A:
Play with your retrieves. I have noticed that in different lakes, at different times of the year, and different weather patterns the fish react differently to the speed of action of these things.
Most of the time I do a slower retrieve using an ultra light setup (4-5lb test line).
The getting off part is really getting to know this lure. I have found that when fish grab hold you really don't have much time to set the hook (I suggest replacing the hook with better quality as well). Unlike soft baits that are loaded with salt or scent, once the fish gets one of these in its mouth they instantly know that its not what they're looking for. Make sure you're line and rod setup are geared towards sensitivity and you will notice a big difference in your ability to land fish.
Never landed any trout on them... almost never land any using any lures because the lakes in my area really don't have any outside of the small qty that the DNR stocks from time to time.
Don't give up on this lure, once you find a method that works you will love them.
