I have worn out quite few sets of 908RRs and the front cant be a little vague and wobble a bit at highway speeds when new but after a few hundred miles it goes away. If by death wobble you mean losing control of the bike and nearly crashing? I've never had anything like that happen and no steering stabilizer on the bike. They are by far my favorite tires for the 990 but I wouldn't recommend them for pavement commuters as there are better choices for that.
