I went to my show yesterday and shot the spyder 30 & 34, Spyder Turbo, and the G3 Element. They all shot great and the cams are nice and smooth. I have a 2012 Vector Turbo.
The draw cycle on the G3 Element was really smooth and felt like the 2012 but I think it had a little better back wall IMO. It was really quiet also. I think the big plus is the wider limb width. My shop manager stated there much easier to tune and there suppose to help with torquing when at full draw.
Call your local shop and ask when the area sell's rep will be bringing them in and go shoot it. It's still a great bow IMO. Also the speed on them are a little faster per my shop manager than advertised.
