World Contest - Open Class

Was looking over the entry sheet for WGC 2017. The open class seem dominated by 21 meter ships. Only two 23 meters (new generation open class) and four EB29. Nary a Nimbus 4 or ASW-22. Shame these beautifully ladies of the sky are not competitive with even the 21 meter birds. There is nothing like flying a 26.5 meter bird, they will stay in the sky on a breath of hot air. Their shape I find so much more alluring than the stubby wings of 21 meters or less.
