You betchya. I find that nickel blades don't produce nearly as much as gold blades. The reason being, in my mind atleast is, we don't have a shad population and I think the bright flash coming from a nickel blade tends to spook the fish. I do use them and have had success, don't get me wrong, but a gold blade would be my first choice followed by a painted white or flourescent orange blade in low light conditions. Right now the flourescent orange has been money, kind of like the "shock" color of yesteryear...LOL
My spinnerbaits have a snap instead of a split ring attached to the bearing, so I can switch blade sizes, shapes and colors quickly instead of switching skirt colors which can be a bit more time consuming. I'll often run through a process of elimination to find which blade the fish prefer.
