sleeker I have never had any problems with using crappie nibbles stopping the action of the plastic bait we catch more fish when I use them also we use pieces of crappie is probably the most deadly yes unattractive that you can put on with your plastic baits for years I used to fish with cut bait off of crappie and I've caught hundreds of fish doing it so if you catch one and your not catching any more caught up the one in try we you she use a razor blade to cut little thin strips this is the way we finished many years ago before all the fancy jigs come about and plastic baits I would believe that gas on your hands would affect fishing I do not like any thing like that near my plastic baits or jigs we deftly carry a bar of soap when I go fishing to worthwhile cans after I monkey around with stuff in the boat like gas or oil believe it or not oil from your hands may have a big factor on catching fish it has been proven that the older that we put off this offending to the fish this is something I knew for many years in practice it I seem to catch more Bass when I was fishing for them if I kept my hands clean also crappie I know that may sound kind of funny to most people him what little oil that we have on our hands would affect anything but it does it's the same thing when you are hunting we put off the order that is offending to animals course they do not like the smell of humans I you she try to mask my body order I will have campfires in get the smoke on me or we use other natural cents to put on me so see our body is very offending to fish and wildlife especially when I was coyote hunting they are very very Lurie about coming in if they even get a whiff of you.
