Anyone check these out yet? 360+ fps

Our pro shops out in Washington state are saying they proly will not get them till Jan-Feb time frame. I shoot the Switchback XT and am thinking about upgrading to this one. My arrows are at 435 grams currently (due to Washington state requirments) so I'm going to drop down to 350 (IBO) since I do all my hunting out of state anyways. I'm also thinking about using a drop away rest vs a bisket. I'm hoping for better long range groups.
