@M.Guenette Nobody can just tell you which is best, its personally subjective and ultimately up to you to decide. But the rfuktor line has always been developed primarily on high end wheels. 4.6 is considered the peak and then there’s some personal tunes of that. Here is a file containing the original rFuktor 4.6 and also my Delta variation of it. V2 is popular and V3 is better for me but waiting on feedback from DD users.
