Flighted Shafts

I have been reading up on shafts lately and found that there are shafts available in the market with 'FLIGHTED TECHNOLOGY'.

Took a quick look at my irons and found that they are flighted shafts!!! -_-''' (Din know despite using them for almost 3 years... heh)

Question is... what is Flighted Shafts??? Are they suppose to be good or bad for average players like myself???

if i am not wrong, flight shafts are high launching shafts

that from project x website : "Project X Flighted
In addition to the playing characteristics that have made the Project X shaft a tour favorite, the Project X Flighted features an exaggerated change in kick point within each shaft throughout the set to optimize ball flight through the bag. Long irons provide a lower kick point for higher ball flight, easier launch and greater distance, while the short irons have a higher kick point for a lower trajectory, greater accuracy and control."
