Just my $.03 ($.02 American) worth! I adopted Tbran's 3" hose mod on my 20' C62 flex head, and I've never regretted it! Even in heavy, weedy soybeans and barley, this mod has greatly improved the "flow" into the auger. I've just started the soys now and am anxious to see how well it works in the stunted stands of beans (it hasn't been the best growing season, ya know)! Yes Tom, me thinks you'll be ignoring your rigid head next year!
