Hi, I seem to have 2 versions of Double Boomerang by Gene Hubert. Becket The only difference is in the A2 Version 1 A2 ON THE LEFT DIAGONAL ladies chain / Long lines forward and back Version 2 A2 Long lines forward and back / ON THE LEFT DIAGONAL ladies chain. Are there 2 versions being danced? If you call or dance it which version do you do? If there are really 2 versions, what are the advantages or disadvantages of each. Thanks, hoping to call it a week from Tuesday. Rickey Holt, Fremont, NH
