I had one of those Browning Bushmaster bows that tracked from one side to the other during the draw in the early 1980's---let's just say I do not have it anymore..[8D][:'(] POS is a great assessment IMHO.
Steel Cables had their problems too--- tho rugged, how do you adjust the timing if needed?(and most needed it!) Some admittedly had cam adjustments, but nothing beats the simplicity of a synthetic harness when it comes to ease of tuning.
Shoot-trhu and X systems are no problem for a finger shooter once you learn them, and loading isn't bad either, like I said one just has to learn a new trick.
