Are these rotators?

[Ol' Ron]

I don't think you can make a silk purse, from a sows ear, no mater how much money you spend. But if it make you feel better, why not. However, I do believe the fine thread does exert more force on the head, I just don't think it's necessary and only brings the cost up on an expensive build for no reason. All out Bivelle maybe, max boost maybe , 100% nitro deffinately. Daily driver, not so much.
