Looks like inversion ipa from deschutes uses a mix of carastan and crystal. Think I'll go this route!
Yup its toffee like alright, but I am not sure you are gonna get that with the light version of it, specially considering that the plain carastan is already not so toffee like (special B now thats toffee to the max!). I think Ruination has a good balance between hops and malt, perhaps a mix might be a good idea. That would set you in the right path for such future experiments too.
Its actually not a bad idea, I highly encourage it.
