Louisville's deal is basically that a bat comes out for 1 year and then The same bat(specs, metal "type" etc.) will come out for a second year but with different graphics to make it look "new".
If you recall the C555. It was blue and black graphics it's first year and then the 2nd year same exact bat but with different graphics (red and black)
Now the Omaha has been around quite some time and followed this two year pattern like the C555, then in year three of making the Omaha they actually made some change to the type of alloy of the Omaha and that "new and improved" bat was around for year 3 and then year 4 (same bat as year 3 with just different graphics) and on and on.
I think the Omaha is now in it's third generation or starting the 4th
It's easy to get caught in all the hype of bat specifications and alloys but the bottom line for high school and college play is bat exit speed ration (BESR) certification. The purpose of this specification is to limit the spring effect of all bats in order to protect the players, especially pitchers.
My opinion is that since all bats are restricted by BESR, there is not a great deal of difference in performance in the $150 to $250 range. If a bat exceeds the BESR guidelines, it can not be certified for high school play.
