Maybe someone out there familiar with the better stout kits can use this info to help track a similar kit down.
beeradvocate says the tatonka is an RIS, which should have some level of hop bitterness present. HotTrailer, are you looking for a partial mash recipe or a extract with steeping grains recipe? Also are you capable of doing full boils or only partial boils?
If partial mash then give NukeBrewer's recipe a shot. What he means by side "wort" is a hop tea. When you boil hops in a wort with a high gravity, such as an RIS, the percent of the alpha acids that get isomerized decreases, so to prevent this you boil the hops in only water in a second pot so you get the full bittering effect you need for an RIS. Just keep in mind an RIS is a big beer, its going to take a lot of yeast, and a longer time than a normal stout to be "ready"
Edit: After reading brewtools post and the link I would consider subbing some Black patent and crystal malts for the biscuit, I was going to suggest this before but I'm not a fan of biscuit so didn't want to be biased.
