Not a very good idea to take your date with you to the dropzone for your AFF. You'll be in class and your date will be hanging out watching all the hot swooping and ego strutting on display and you'll end up coming out of class to find your date in the ghetto.
did my 6 minutes tunnel time last night, by the end of it I was fairly stable and could do some turns using my hands.
For the first 3 minutes I had my arms too low and my hands infront of my face rather than higher up and out. As such I was bouncing round all over the place and it was not fun. Once the coach told me to hold my hands higher above my head and straighten my legs a bit things felt better. I also think I was arching more from my chest rather than my waist... things to work on!!!
I think that because the tunnel is such a confined space (compared to a jump) then you are VERY aware of mistakes and loss of position. I think this is a good thing but also dents the confidence a little.
