The only problem with that, like in the COG case, is you only get one value returned. To adequately use a COG strategy, you need the actual COG plus the value of each of the 5 lines....iCustom won't give you that (unless you found something I don't know about).
Something like an IFT is ideal for iCustom - that is, IF you can get the value to return correctly. I am getting an overflow on the one I have....
