I have been interested in these starting last year but took the conservative route trying to stay with fixed blades. My problem at 354 fps its hard to get the fixed blades to fly. My brother was successful with similar setup but he shoots different arrows. I shot swackers last year they are ok probable 1/3 larger group at 80yds. Which model do you have I am not sure if I want to go with the 75 or the 100. The 75 has an aluminum body with a titanium tip not sure if I trust an aluminum body after testing a couple mechanical's that sheared off right behind the chisel point hitting the edge of a 2 by 4.
