Hehe :p I'm not much experienced when it comes to kennen, just figured out that if you mark them with LR throw the TS and finaly stun with ES. Then there is another stun when you pop your ulti (3 hits per enemy, 3 marks, stun). Stunned all 5 opposing champs so my team could help ganking :) Pretty awesome :D

This is an excellent build in my opinion. HOWEVER, it is also for more experienced players, because I tried the same things at level 5 and I kept getting ganked over and over again. Partially due to my team and partially due to a lack of initial kills - people were savvy to what I was trying to do, and I ended up taking a dirt nap awfully fast from stun effects.
