Innis and Gunn Rum Cask extract recipe

I just tried crafting a recipe with the beersmith free trial (pretty nifty software, might buy that one...) and came up with the following.

Can anyone take a look at this and let me know if it sounds like it will be decent? I know it will be beer, but I just want it to be a clone of Innis and Gunn rum cask, and to taste really close to the real thing (which is $3.25 a bottle here! I'm way too poor to buy a lot of the real stuff!!).

Thanks in advance,

Its been a while so I hope you remember. Did this recipie turn out the way you expected/ hoped?

I never did make it. Got distracted with a gazillion other brews, and this fell off the map.
