New player, advanced bat.... What to do

Hi guys I'd like to start by thanking you for all you've done and continue to do.   I recently started playing TT and have really gotten hooked in the last few months.  I started with the cheapest preassembled bat I could find (stiga optima I believe) after about a month or two I foolheartedly decided I was Ready for an upgrade.  

After a few days of online shopping I found the bat I wanted.... The killer spin diamond Tc premium, a 250$ preassembled racket.  It's been a couple months now and although I have gotten accustomed to the lightning fast bat, I have very little control when receiving service and just in general....  I'm still in the early stages of learning this truly amazing sport and feel my "advanced" setup isn't condusive to this.   So what should I do?  Put my expensive bat on the shelf and hold off while using something a bit more user friendly, or stick to my guns and continue forward with my lightning rod?      Thanks so much guys and keep it up.
