Sounds a little heavy of draw to start with. other than that, the bow is perfectly fine.
Mech heads offer easier tunning...but you shouldn' t SKIP tuning just cause you got mech heads. Modern ones kill deer dead.
Fixed blades offer peice of mind KNOWING the blades are " open" from the start.
Both penetrate and both can kill deer quickly and cleanly, and leave a good blood trail.
Shoot what you like.
