I bought a Pearson Cougar a few weeks ago off of ebay to help me with the trad learning curve while I'm waiting on my Chek Mate Hunter II (that I ordered yesterday). When it arrived it had a few surface scratches but nothing to worry about. Today while stringing it I noticed a patch of small light colored lines running the width of the top limb. They haven't broken through the surface, and I shot about 50 arrows with no change. Are these stress marks? If they are, is the bow still safe to shoot? The limbs are strait, and the tips are good, I just hope it can hold out until my hunter II makes it in later this year.
