I used mine (CA - SM18) for 5 seasons and
retired it. I have many fun memories and innings with that bat. I can still use it if I wanted but the bat (Keeley Blitz shape, no stickers) that replaced it feels like butter in my hands.
Regarding my old trusty CA, it looks like a bat that has seen action - cracks, splits etc. I had to glue and sand some cracks but nothing serious...just battle scars. It is still great and goes great guns.
