I would recommend to add it to your flex head. We have 2 J.D. combines that we run 30's with no countour master on them and a 2166 that has field tracker, the first year we ran a 25' and now we have a 30 on the 2166 and it does a remarkable job with the field tracker and cuts alot better on uneven ground, the next new J.D. I get will have the countour master on it, so I think it is worth trading your head on especially if you have any dips or uneven ground. I do not think it is worth it on a corn head unless you have rolling ground or someone that is inexperienced running the combine in corn.
