Assuming that the frame is well cared for, what is the average life expectancy of a frame. By that I mean, how long does it last before its playability starts to fade. The other day I was picking up my new LM Prestige mids and took in the Prestige Pro Id been using. The Head rep saw it and asked if he could have a hit. After doing so he said to me that the frame was dead or, at least, was no longer able to provide the same levels of feel and power that it should. It is a 15 year old frame that I bought from an op-shop so he may well have a point. I always thought it was a little dull but assumed it was just the 16 gauge strings. However, Ive been playing and winning at quite a high level with it so didn't give it much though. In hindsight Im wondering if that explains why I felt the LM Prestige had twice the power of my old Prestige Pro, why I have to string the LM 15lbs higher and why I had to work harder for spin and power with the Prestige Pro. Im curious to know if that is something others have run across or have any idea about.
