Coming from someone that own's five bows with "unlimited warranty" I don't think that you've made an unfair statement Wyvern. As was said by you know who "it's not how fast a bow is it's how long it's fast". One has to wonder if one, were the warranties are killing them and number two is one year the only risk they are going to take?
Edit/add: Companies frequently make risk management decsions based on knowledge. Any car maker knows how many heat cycles a cylinder head will take before cracking. I cannot imagine that any bow maker does not study how many cycles a bow will take before failure. The predicted failure rate (expected warranty cost) is factored into the price as well as the length of warranty. If a car maker knew there would be zero warranties for on million miles then the warranty would be a million miles and they'd outsell everyone.
