yeh i found with mine that sticking a round corn plaster over the mic helps cut out the wind noise to almost zero so you can just hear the motor.
also its difficult to show the vids in 1080 as youtube reduces the resolution to 720.
the only benefit the gopro has is the watertight cse compared to the drift's rubberised housing, but mine hasnt seen any ill effects from rain or jetwashing!
(forgot it was there lol)
another good thing on the drift is it has a standard tripod mount so you can use any camera accessories with it unlike the gopro.
i got a top suction pad for mine off ebay for a fiver
will be some good footage at this years wales bash then - ive got a 16gb card in mine, unlike the 30 min vids on the gopro this thing will record all day.
