I like the Allianz income riders, especially the MasterDex 5 Plus,for the increasing payment feature and the cost. The CPI linked increasing feature on the MasterDex X product is one I just used this week with a Client. I have used the Aviva line a lot in the past and Midland National's to some degree.
With the recent decreases in income rider rates for some of the more popular carriers I have been having a lot of luck with the different riders with Phoenix because they beat the payouts on American Equity and Allianz now. And when you add a 10% premium bonus all the way to age 85, it's tough to beat it at the older ages.
We are starting off 2011 with some proprietary products and if you other IMOs are interested give me a call because I'm looking to set up more partnerships for these niche FIA products.
