I am shooting and prefer the QAD HD (having shot the LD and the Trophy Taker previously).
It offers full containment without the LD limitations which include:
- Not full containment
- The actuating string is about 3x longer than with most drop aways so it is a liability (gets caught on things).
- The attaching method to connect the string to the limbs is inferior - cheap plastic part; cannot be served.
- The string relaxes at full draw and can appear in the sight window.
- The rest is very wide and will not lie flat on the curved sight window shelf of a Bowtech or Elite.
With that said, there are a lot of folks that prefer the LD.
