DeMarini CF4 what the difference

[CarmineM]

I keep hearing that the CF4 is one of the bats of choice on here and other boards.
DeMarini has 3 bats for 2011 what is the difference in the bats. Their site doesn't really tell you

DeMarini CF4 ST (-10) Fastpitch Softball Bat,
DeMarini CF4 Insane (-10) Fastpitch Softball Bat
DeMarini CF4 Hope (-10) Fastpitch Softball Bat

Isn't the insane end loaded and the hope bat the pink one?

I'm pretty sure that's the difference too -

Hope = Pink color CF4

Insane = End loaded
