While the xtec and VTEC share similarities the risers are the big difference. The VTEC has a frame totally engineered to take away bow input to a shooter. The ideal for the VTEC is to reduce all vibration and shock which gives the shooter feedback. Less vibration and shock smoother shooting equal more accuracy. The Sims Vibration Principle.

I personally like the less feedback given from the VTEC riser. I thought yeah right whats the difference in a riser. The VTEC makes me concentrate more on the pin and less on the grip allowing for no occassional bow torque and drifting arrows. I traded a Havoctec and bought the VTEC. I therefore am happy now.
