where it lands, how it flies, how slim, how much tungsten, how well it groups, etc.. is purely placebo. if there's somethin' you wanna change on your dart to to make her sexy and appealing. DO IT... if you don't, it'll be reflected in your throw...your conscious self.
the mechanics of the throw will take care of itself. consistency is achieved by no longer thinking. by letting muscle memory and your subconscious do it's thing. the hard part is the mental aspect... which many wrestle w/ due to trends. if it looks good, feels good, you'll do good.
taylor throws the heavier tons for a reason. cuz they have a positive feel in his hand, look intimidating... and hit the board w/ fackin' authority ..THUMP. hell yah i wanna throw that.
at the end of the day, all that matters is how sexy she looks, and how good she feels.
