Most bow companies offer lifetime replacement of machined risers, limb pockets, and eccentrics, the only thing not warranted for life are usually the limbs, and they usually have at least a 3 year warranty. If they do not fail after 3 years of normal wear and tear, chances are they are not going to fail anyway.I have quite a few bows that have been around here for over 10 years,(some over 20) and they all still shoot just fine. I really do not see what all of the hoopla is about other than it being simply a new angle of marketing hype, it really is nothing that new or different. Nothing against Hoyt or anyone else, but if you really have to worry about parts replacement to the point where this actually makes a difference to you, it looks to me like you have little confidence in the equipment you are shooting. This is not good, one must always be totally confident in themselves and their equipment for best performance from both. I for one would never switch from a bow that I shot very well and had confidence in just for the sake of a lifetime warranty on limbs that for the most part would never be utilized. To each their own, but don't let the hype suck you into something that really isn't all that big of a deal nowadays due to better technology and materials. Just my own thoughts, Pinwheel 12
