I' ve shot my Mathews about 250 shots and the serving on the cam is already wearing.... whats the deal with that????

That my friend is the nature of the Mathews Perimeter weighted Cam design, and poor servings. You' ll have to deal with it, and constantly repack your serving.....or reserve with a tighter/better material and hope it holds.
The inevitable string stretch doesn' t help either.
The serving on my Ultra Max looked like it was in a dog fight after a few hundred shots.

Should have bought a Hoyt! J/K

I second Hankfan... should have bought a HOYT lol

While I also shoot Hoyts, my advice is to invest in a better quality string and ditch the Zebra.

Mine did the same things. I shot great groups one day and the next day missed the target on my first shot. I measured my axle to axle and it had grown 3/8 inch.

take it to the pro shop and have them reserve it, and it will last longer then the original one... It will still come apart just not as fast... But that' s just the nature of the Beast...

well maybe mathews, with all their HYPE about there GREAT BOWS, should put a little better string on them, consider you pay 700 for the bow...

just my 2 cents
