Split strings used to be more common but in our quest for ultimate speed, we have gone to no splits at all, even pistol and when someone writes one or is given general instruction and decides to do one, we have problems with it. I like to write stages that give folks choices so they can shoot the stage in a way that best suits their own style and right or left-handedness (mostly because I shoot long guns left-handed). I love to give options and see what folks come up with.
