I did not notice any timing or synch. issues with the Pat DC that I had in my possession...even after quite a few shots. As others have mentioned the issue of string stretch is not as much of an issue today as it was even 5 or 6 years ago. Balance is excellent on the new '04 model and the speed is there as always.

My only 'negative' is that the draw cycle is a bit stout and the valley is a bit narrow. Going with a 60 lb peak weight model makes both of these issues much more manageable.

Hope this helps.
