I think IAHBE is great, but I would not recommend it for new affiliates. There is an awful lot of information and training in SFI and until you understand SFI you will not have the proper time to benefit from IAHBE. After you are comfortable in SFI then it would be good.
I would recommend a combination of TCredits and S-Builder for newer affiliates. They will be able to build their team and also have TC for PTP, auctions or their T Connect store ect.
