This driver is arguably one of the best drivers in the modern era, especially for the price. You get excellent ball speed and forgiveness on mishits, adjustability with on the hosel and weight variability in the crown to suit your swing.
I went from a Taylormafe R15 to the Sim2. I think the SIM2 may not be quit as long but that could just be the new ball I'm using. But It is way more forgiving on off center hits and does not spinas much resulting in less slice. If your swing is good but not perfect this club is for you. Its not gonna a fix a bad swing though so don't expect that.
