I like this list, im sure it looks pretty impressive on the tabletop! Down the years ive heard players saying Kans are not 'all that' and so on, but i rekon like most things in 40k, with proper application (and extreme numbers!) they are pretty darn powerfull! Your enemy will need alot of Strength 5 or better weapons to shoot them down, and if they assault them i presume they are one helluva tarpit! Would love to see this army fight Tau or Imperial Guard.
