Demoknight is much more effective than sticky demo. I have been playing for 2000+ hours and I assure you I can shoot sticky's with the best of them, but I still think eyelander demoknight is much much better...Here is my source op profile http://sourceop.hlstatsx.com/player_skill_graph/180040 where you can see I have better stats than the #1 player (or anyone else for that matter) who uses sticky demo. Demoknight has much more survivability than sticky demo and just as much killing power, if not more, if you know how to use him. As you can see my avg k/d with demoman (demoknight) is 10, compared to the #1 player who's k/d is 5...Also you can see I have more kills per minute than him. Demoknight>sticky demo, if you ever want to test my claims out come fight me on source op or nemu goldrush :D
