The only yeast I've ever used in my oatmeal/chocolate stout has been WLP004 Irish Ale yeast.  I have some Kveik in the fridge (dry packet) that I may try out on it next time.  The WLP004 tends to quit a little early, IMO.  Either that, or I'm not controlling temperature well enough in the mashing.  I figure I'm getting too much unfermentable sugar in the wort somehow. and rarely get below 1.025 with the FG.  I think the Oatmeal/Chocolate stout would be a bit better with a dryer finish.  Thanks for the ideas, guys.
