Very different bows. I like the Z7 because of the extra weight and greater stability. Just an easier bow to shoot because of the weight. Both can be just as accurate.
I do like the weight of the z7 for 3D Shoots. The lighter bow is going to be easer to carry while hunting. Any other thought out there on the too bows. Z7 or Mathews heli
I got to do some with the Heli bow. 340 fmj at 29 in. 470 gr. bow at 63 lbs. Bare shaft and 2in blazer with field points , and broadheads same group at 30 yards, A little fine tuning this should work.
