Whats your favorite spinnerbait blade and why?

Depends... I like Colorado blades in low light or murky water or for more thump or when I want the bait shallow. I like Willow blades if I want the bait deeper or if I want more flash and less vibration. Indiana is in between the two for vibration and flash. So it's easier to bulge a Colorado blade and you can reel a willow faster in deeper water. I usually use gold when it's overcast or murky and silver when it's sunny or clear to stained. Needless to say, I have a pretty decent collection of spinnerbaits!
