The Orbit reel does work that good and with our's I see no need for a full fingered auger. I know that Agco does offer the Orbit reel and I have yet to talk to anybody who used an Orbit reel say it wasn't worth the money.
used an orbit reel on an full fingered 8200 last year. had a heavy tall green soybean crop. full fingers feed the material under the auger and feeding is very constant. At times the fingers would pull a large slug in and break off. tried a orbit reel on a 1020 this year totally different conditions but felt that it kept the cutter bar clean still having problems with the corp riding in front of the auger i think full fingers would help. I like both on the gleaner head.
