With the longer geared 6spd, I'm sure this has changed quite a bit. I'd still say that redlining 1st and 2nd makes sense because you probably still put down more torque at 6500-6700 rpm in 2nd, due to gear multiplier, than 4xxx/5xxxpm in 3rd if you shift earlier at 6K.
Deciding to shift has almost nothing to do with power... it has to do with time lost from upshifting and downshifting. While the situation is better in the 07+ cars, there are still plenty of sections that put you "in between" gears.
