FE and Med Supps are two different markets. You will have a few cross-sells, but don't count on all of your clients buying both products. Pick one and go with it. I've focused on both products in my career and had less than 15% cross-selling to the other product. Very different clientele between the two.
Sorry to hear that, but if you would have focused in on MA Plans as well, you would have sold more FE. If it's worked correctly, you should do all 3, Med Supps, MA's, and FE. IMHO.
