I have a bat that is 5 years old now. Couldn't tell you when it reached its 'peak' as such,, but it has been a gun for a while now. I have looked after it and not used it in the nets too much, but it has scored me a lot of runs (of my 13 scroes of 50+ for the club, it has gotten me 11 of those with 2 centuries in there). It is still a gun to this day but for whatever reason I insist on buying more bats even though I can never bring myself not to use the old faithful and when I do and get out cheaply, I know it's the old bat punishing me for not being loyal hahaha.
