Can someone explain what the front would be would it be the close to the lead head? or the last blade? any pics of a similar bait would be nice thank you and sorry for the basic question 

 a Gold Colorado Blade on front, in a #3-4 size, with a # 4 or 5 Willow Leaf

The 'front' blade is closest to the lead head and the 'back' blade will be one the end of the wire.

Here's a small Colorado blade on the front with a larger willow leaf blade on the back .

Any advantage to this style than double willow or a single Colorado?

Each blade type & configuration offers different qualities.

Knowing what they are & how that can benefit each presentation can be helpful.

 Here some info from the BR articles section . .
