I've been shooting cutter for almost a year now, and am down to 3-4 shots for the turns, rather than the 6-8 I took during my first couple shows. I haven't had a chance to try singles for these shows, but have a show coming up n the 26th I had planned to shoot that way, at least for a couple of turns on a couple horses.
Since I know I can get shots using the short burst method, I want to use that for the majority until I know I've got my timing down correctly. I had two full days to practice reining horse before I had to shoot the show last weekend. Since my boss' livelihood comes from selling pics, and I had no choice but to shoot singles that show, I need to ensure I've got it do win before relying on that technique.
I currently use a Nikon 80-200 f/2.8, and most of the pens I shoot at about 80-100' from my position, depending n how far out the rider cuts the cow. Settings are 1/640 or 1/800 at f/6.3 -8, depending on the pen and cloud cover...
In thinking about it, the roping events have the most unpredictability to them, since there is no pattern like reining (or even reined Cowhorse) or the nearly-constant focal plane distance of cutting horse events. They are all over the place. That's probably going to be the biggest challenge.
