IPM vs tapioca starch in lotion

[cerelife]

I've always used tapioca starch to 'cut' the greasy factor in whipped body butter and lotion, but I bought some IPM during WSP's big sale based on the glowing reviews on here of how good it feels in lotions.
Per WSP, you can replace tapioca starch with IPM or combine the two.
I was just wondering if anyone had a preference for one or the other - or a combination of both?

I'd love to hear from people on this too. The black cat in your avatar is gorgeous. We have a black cat as well. She's 16 years old and has white whiskers now but is still going strong!
