I have used Satin Ice very successfully. I lost an entire tub of Chocopan when I laid it on a cake, and it stretched, pulled, ripped. It was a mess and couldn't be salvaged! I have also used FondX but wasn't super impressed by it, particularly the colours. I have tried Duff's, which I know is the same as Fondarific, but it is expensive (without the coupon) and doesn't come in as many colours and flavours.
I like how Fondarific holds up while kneading, covering, and smoothing. I also like the taste. Not sure where I can get it in Ontario (GTA area) now that Golda's isn't carrying it ... thanks for any help you can provide.
