Its your car at the end of the day and if you want to rattle it you can and good luck to you, you've had experience of it before with your other car so you know what you're doing. You asked for opinions in your opening post on rattle Vs pro so I'm afraid you're gonna get a mixed bag of responses from here, mainly on the side of pro though, which will cause some people to be quite vehement in their opinions i'm afraid. As long as you're happy with it and can live with, who cares !
