Share 'Fairway and Distance Driver Situation'

So why is it that I'm throwing my Tee Bird and TL the same distance as my Destroyers and Force?  I feel like the natural reaction would be that I don't have enough power to be throwing a disc like a Destroyer, but I'm throwing around 400'-430' with my Tee Birds, TL, Destroyers and Force.  Not really that big of a deal, but just wanted to hear your opinion.
