Hi all
Just to make sure that this gets right: The Skydive-U or BBF system also teaches other aspects like exit, canaopy handling and a lot of other things.
Having been through both the WARP and BBF as a student my experience is that the WARP will get you safe in the air, but the BBF will make you a better flyer.
I completely agree that the quality of the instructor will determine the quality of the education. I guess that this is true in all aspects of the sport. Keeping up to date is extremely important and in order to keep a Skydive-U rating you need to be current.
PS. I am a Skydive-U coach.
