Get the Scootworks front pully. You'll be glad that you did. Much more comfortable all through the range. Vibration, power, need for an extra gear, etc., is all personal feel and subjective. I had all the same complaints as you. I put the Scootworks front pully on and love it. Not just at 65 mph put all the way through the range. I think I'll put the back one on as well.
