Problem with my racket

Sir, when i first started using my bat (Markv and Joola smart on Joola carbon blade) It was faster than my previous pre-made bat. but now, after a month I'm feeling my bat has become a lot slower. What is the reason, sir? 

Hi Earl,

It probably hasn't become slower but you are just getting used to the pace of it so it feels slower.  If you go back to your previous bat you will see the difference.
