I have shot the Cybertec with Versa and Excel cams. The listed 6.5 inch brace height was actually closer to 7 inches on both bows with the limbs bottomed out (6.75 actually).
I did not notice a discernible difference in accuracy between the Havoctec and Cybertec when shooting both at the local indoor range....but, the indoor range isn't out in the hunting woods...<img src=icon_smile_wink.gif border=0 align=middle>
