Report Molly's agility thread. in Obedience, Agility, and Flyball Posted September 23, 2019 On 9/19/2019 at 1:58 PM, CptJack said: A NADAC switch is essentially a OMD tandem turn. Or,rather, a tandem turn is a kind of switch, I guess. I've used them on AKC style courses, but I definitely don't disagree international courses are a whole 'nother ball game! OneI know nothing about and play very little. Independent backsides sound super fun though! Hard! But fun! I started in NADAC, its not really a tandem turn, as its taught as a change of lead, I think what makes it so unique is that it is primarily used on the flat as a change of direction, I have watched NADAC masters use it well and always loved it. There were many things I hated about NADAC but I always loved the switch command.
