I have an 05 Patriot and no problems.
Two guys I shoot 3-D with used to shoot the Bowtech Alliegance. (key word, used to) and they each had two sets of limbs split down the center on the cam side. One guy could not get consistent groups and found the crack upon further inspection. Both guys are speed freaks 320+ FPS with their set ups and both had long draws 29-30". Dont know if that was the cause of the crack. Bowtech was good about the warranty and sent new limbs every time. The guys sold their Bowtech bows and went back to Mathews. This design flaw could be the reason for the new split limb bowtechs.
I also bought a Switchback XT instead of another Bowtech because of their problems. I'm not to impressed with my new XT, for me it shoots average nothing special, but it will shoot better than my ability like many of the other bows out there.
If you guys get a chance shoot the Bowtech Guardian, I thought it was the smoothest shooting bow i've ever shot.
Just my 2 cents. Good Luck this season.
