Just got intense squares and rounds last week, their sitting in the box still waiting to go on. I figured dog bones only wouldn't vibrate at all, their not even loaded against the chassis sitting at idle. A few years ago we built a dsm with full prothanes all the way around, no balance shafts and big cams. It was miserable, the keys jingled in the ignition at idle and the engine would resonate through the steering wheel and make your fingers numb.
