The Sensei 310 seemed to have one of the best 3360 implementations I've ever tried, so I would probably try a Rival 310 with same sensor if I was you. I haven't personally tried the Rival, but I assume it controls the same as a Sensei 310. Not really sure if it's actually smaller than a Deathadder or not. Maybe by a few %. I'd be using the Sensei 310 myself right now if the shape was better, but they made it a lot worse than a regular Sensei shape.
