Killian's Irish Stout Combo's

I picked up some Killian's Irish Stout a little while ago.  I was familiar with their Irish Red but had never tried the stout.  I was predicting that it would layer like Guinness or Murphy's but I was wrong. Turned out to work well as a bottom layer much like porters. 

Based on this stout, and others that I've tried recently, I think I'll need to revise by general beer layering rules a bit.  Stay tuned.
