I am in no way an expert, however the ultra mag was my first bow and i have a vipertech now and my cousin shot a ultra tech, out of the three the ultra mag was the quietest and the lightest with the magnesium riser.
I sold it to my brother and we intalled a set of gibblet strings on it this year and i tell you it is a great bow, it is ultra quiet and he drills with it, so if the lazer tech or the highlander are this years and last years bows I dont think you will go wrong.
my two pennies,
good luck and good shooting
