Sorry...my lengthy, highly technical, witty and entertaining post somehow didn't make it through the Strait of Hormuz server at BF....and now I forgot what it was. Gotta remember to copy anything I post on our temperamental server.
Let's see, in one sentence here goes. Behind a reliable, known partner (especially if big and broad), I sometimes like to draft maybe 18 inches off his wheel. For others I'll drift back farther. When I get back something over a wheel length, there seems no point. Assuming a frontal breeze or even a calm, where do others find themselves tucking in?
