i have a 2001 magna tec. i just bought the 2003 ultretec. afterm about 10 shots i had the ultratec zeroed in and have been shooting 2 inch groups of 5 at 20yards. do to string strech i have not even tried to paper tune the new bow yet. i am very happy with my choice of primary bow and secondary bow as far as that goes. 360 grain at 65 pounds 273fps. hope this helps. the 2 bows have the same ata but the riser on the ultratec is longer. for me this could be a problem as i have built all of my bow holders to fit my magnatec. i sure hope i do not have to take down all of my stands and modify my holders. that will be a lot of work.
i chose the ultratec over the cybertec because of the brace height. the cybertec is a faster bow. my ultra tec has the cam and a half not the spiral.
