Phantom 2 9450 composite or metal hub?

[UnknownCaller]

I have a modded orignal phantom 2 vision with T motor 2214's which I use solely for long range flights. I recently installed 9450 composite hub props. I normally get 20 to 22 min of flight time , but I have been noticing a slight decrease of flight time since the switch. This is over 4 different limefuel 6000 mah batteries one of them brand new. I heard the composite hub has more give then the metal one does this translate into less flight time?

Have read where many users found that the composites gave less flight time and performance. Stick with the stock props and you be better off. The are engineered with the proper pitch and flexibility to give the best performance.
