Many thanks for all the replies.
I have about 1000 jumps, so I will try out your suggestions after my neck has recovered sufficiently.
I've had a sabre 1 for a long time and it's been a great canopy (I used to shoot a lot of video too) but it gave me a good slam the other day after some work was done it. I probably just need a smaller pilot chute, but I think it's time for a new canopy anyway.
