I have a parker and my dad has 2. All are 2012 models and older. The only issue we have had is mine split the limb last yr, was replaced under warranty. I personally look at it this way. I spent about $400-500 each for these bows. Only had 1 issue. Its possible I could have another issue this week, or 10 years down the road. Whats to say the front end I buy as a "spare" won't have an issue either. It could last a month, or 10 yrs. I'm just going to opt to use my bow as long as I can and whenever the time comes it breaks I'll just buy a new one at that point. I'm sure by that time the bows will be more advanced, etc....at least that's my hope and plan.
You can't bag a big one if your not out tryin
