Yeah I agree with you about Devlin to a certain extent, the guy can bar and he has a lyrical depth you don't often see in grime, but his delivery is way too monotonous for me, he needs to slow down once in a while! I don't have the Art of Rolling but I used to have the first mixtape 'Tales From the Crypt', it was deep.

JuJu's pretty annoying but he's on another level production-wise. I think he's had crossover success with the scene kids because of his clear delivery, he's accessible. The 'serious' thing yeah... lot's of MC's had catchphrases down the years lol.. heard of Flirta D?
