Nice vid, perfect sets. And yes it would be very good to get a downwinder with that view even better some downwinders and you in between DJ so we could pick some technique cheers.
I was speaking to Matt holder (reflex films) earlier in the year about his new chopper and he mentioned you can actually get a device and program it so that it sits a certain distance away from you and just follows you along. That distance could be 2m, 5m whatever you want it to be. I reckon that would deliver some pretty good DW footage.
