Dolly launches. I have limited experience with them and I don't
like them. Of course, you'll think, you're writing this after
Julia's incident.
But Jamie, Dave and others at Quest will know I've expressed my preference for
foot launches before. And
I've written about my concerns about dolly launches with the tail before. So
why am I writing about it now? Because I have pictures of my tail and because I
am reflecting on my first serious series of dolly launches. Of course the second
reason may well be triggered by the incident.

So why don't I like them?
