I have a 2010 Hoyt turbo hawk. I have it shooting well and very accurately for fun. Out to about 50 yards I can reliably put 4 of 5 inside a 9"circle. Inside 40 yards I can do that to a 6" circle. Inside 30 yards inside a 3" circle. Here is my question, as a recreational shooter when should I consider a new bow? Is there a time or shot limit for the limbs or cams? I have a hard time (to me) justifying spending over $1000 for a bow that shoots only 20fps IBO over what I have (320 vs. 340). I just don't know if I would really see a difference. I change out the strings and tune it every two years or so even if the string is well lubed and shows little wear. I pay for the best quality strings and serving offered. Just asking before I put it in for tuning and string change next month. Edit: About when does a bow start to show it's age in terms of dimishing performance and how might that be seen? What is the lifespan of a compound bow?
